The novel posits that space around the Milky Way is divided into concentric layers called Zones, each being constrained by different laws of physics and each allowing for different degrees of biological and technological advancement. The innermost, the "Unthinking Depths", surrounds the galactic core and is incapable of supporting advanced life forms at all. The next layer, the "Slow Zone", is roughly equivalent to the real world in behavior and potential. Further out, the zone named the "Beyond" can support futuristic technologies such as AI and FTL travel. The outermost zone, the "Transcend", contains most of the galactic halo and is populated by incomprehensibly vast and powerful posthuman entities. A human expedition investigates a five-billion-year-old data archive that offers the possibility of unimaginable riches for the ambitious young civilization of the Straumli Realm. The expedition''s facility, called High Lab, is gradually compromised by a dormant super-intelligent entity (actually encoded within the archive) later known as the Blight. The Blight rapidly learns how to infiltrate and control the computer systems of High Lab, and even develops the ability to possess and control the living humans. The novel starts with an imaginative description of the evolution of this superintelligence through exponentially accelerating developmental stages, culminating in a transcendent, nigh-omnipotent power that is unfathomable to mere humans. Shortly before its final "flowering", the changes in a single minute of the Blight''s life are said to exceed those of 10,000 years of human civilization. Recognizing the danger of what they have awakened, the researchers at High Lab attempt to flee in two ships. Suspicious, the Blight discovers that one of the ships contains a data storage device in its cargo manifest; assuming it contains information that could harm it, the Blight destroys the ship. The second ship is allowed to escape, unharmed, as the Blight assumes that it is no threat; but later realizes that it actually held a countermeasure, one of the few things in the universe that the Blight fears. The ship lands on a distant planet with a medieval-level civilization of dog-like creatures dubbed "Tines", who live in packs as group minds. The ship is revealed to be a sleeper ship, carrying most of High Lab''s children in "coldsleep boxes". The boxes are rapidly failing and the surviving adults begin unloading them, but are killed when one of two rival forces of Tines seize the ship. The faction that initially contacts the humans, led by a Tine known as Steel, kills the adults and destroys many of the coldsleep boxes. They also capture a boy named Jefri Olsndot, whom Steel intended on killing but eventually exploits in order to develop advanced technology (such as cannon and radio communication). Jefri''s older sister, Johanna, is rescued by Pilgrim and Scriber, wandering Tines who bring her to the rival faction, led by Woodcarver. She is asked to help develop technology that could gain the upper hand in the impending war. A distress signal from the sleeper ship eventually reaches "Relay", a major node in the galactic communications network. A benign transcendent entity (known as a "Power") named "Old One" contacts Relay, seeking information about the Blight and the humans who released it. Old One constructs a seemingly human man, Pham Nuwen, to act as its agent. Pham and Ravna Bergsndot – a human employee of Relay''s owners, the wealthy Vrinimi Organization – trace the sleeper ship''s signal to the Tines world. Old One designs a vessel, the Out of Band II, to reach the Tines world and to investigate what the ship carried with it from the High Lab. The Blight attacks Relay and Old One. Old One gives Pham the information necessary to activate the Blight Countermeasure while dying (a process known as godshatter), and Pham and Ravna escape Relay''s destruction in the Out of Band II. After arriving at the Tines homeworld and allying with Woodcarver to defeat Steel, Pham initiates the Countermeasure, which extends the Slow Zone by thousands of light-years to enclose the Blight. This ends the threat of the Blight at the cost of wrecking thousands of uninvolved civilizations, causing trillions of deaths and potentially the extinction of several galactic races. The process also kills Pham and strands the other humans on the Tines world, now in the depths of the "Slow Zone" where rescue by an advanced civilization is impossible.

A Fire Upon the Deep

Beginning several months after the events in Blade Runner, Deckard has retired to an isolated shack outside the city, taking the replicant Rachael with him in a Tyrell transport container, which slows down the replicant aging process. He is approached by a woman who explains she is Sarah Tyrell, niece of Eldon Tyrell, heiress to the entire Tyrell Corporation and the human template (templant) for the Rachael replicant. She asks Deckard to hunt down the "missing" sixth replicant. At the same time, the human template for Roy Batty hires Dave Holden, the blade runner attacked by Leon, to help him hunt down the man he believes is the sixth replicant - Deckard. Deckard and Holden''s investigations lead them to re-visit Sebastian, Bryant, and John Isidore (from the book Do Androids Dream Of Electric Sheep?), learning more about the nature of the blade runners and the replicants. When Deckard, Batty, and Holden finally clash, Batty''s inhuman fighting prowess leads Holden to believe he has been duped all along and that Batty is the sixth replicant; he shoots him. Deckard returns to Sarah with his suspicion: there is no sixth replicant. Sarah, speaking via a remote camera, confesses that she created and maintained the rumor herself, to deliberately discredit and eventually destroy the Tyrell Corporation, after her uncle Eldon created Rachael based on her and then abandoned the real Sarah. Sarah brings Rachael back to the Corporation building to meet with Deckard, and he escapes with her. However, Holden - recovering from his injuries during the fight - later finds the truth: Rachael has been killed by Tyrell agents, and the "Rachael" who escaped with Deckard was actually Sarah. She has completed her revenge by both destroying Tyrell, and taking back Rachael''s place.

Blade Runner 2: The Edge of Human

Nine years after Emperor Paul Muad''dib walked into the desert, blind, the ecological transformation of Dune has reached the point where some Fremen are living without stillsuits in the less arid climate and have started to move out of the Sietches and into the villages and cities. As the old ways erode, more and more pilgrims arrive to experience the planet of Muad''dib. The Imperial high council has lost the political initiative and is powerless to control the Jihad. Paul''s twin young children, Leto II and Ghanima, sharing his prescience, have concluded that their guardian Alia has succumbed to possession by one of her ancestors and fear that a similar fate awaits them. They (and Alia) also realize that the terraforming of Dune will kill all the sandworms, thus destroying the source of the spice. Leto also fears that, like his father, he will be trapped by his prescience. Possessed by the persona of her grandfather Baron Vladimir Harkonnen, Alia fears that her mother, about to return to Arrakis, will recognize her "abomination." A new religious figure called "The Preacher" has risen in the desert, railing against the religious government''s injustices and the changes among the Fremen. Some Fremen believe he is Paul Atreides. The fallen House Corrino on Salusa Secundus plots to assassinate the twins and regain power. Lady Jessica returns to Arrakis and recognizes that her daughter has been possessed but finds no signs of abomination in the twins. She plans with them to thwart Alia''s plotting. Leto arranges for Fremen leader Stilgar to protect his sister if there is an attempt on their lives. Alia attempts to assassinate Jessica who escapes into the desert with Duncan Idaho''s help, precipitating a rebellion among the Fremen. The twins anticipate and survive the Corrino assassination plot. Leto leaves to seek out the Preacher while Ghanima, masking her memory with self-hypnosis, reports falsely that her brother had been murdered. Duncan and Jessica flee to Salusa Secundus where Jessica begins to mentor the Corrino heir Farad''n. He seizes power from his regent mother and allies with the Bene Gesserit, who promise to marry him to Ghanima and support his bid for coronation as Emperor. A band of Fremen outlaws capture Leto and force him to undergo the spice trance at the suggestion of one of Alia''s agents, who has infiltrated the group. His spice-induced visions show him a myriad of possible futures where humanity has become extinct and only one where humanity survives. He names this future "The Golden Path" and resolves to bring it to fruition. He escapes his captors and sacrifices his humanity in pursuit of the Golden Path. This requires him to physically fuse with a school of sandtrout, gaining superhuman strength and near-invulnerability. He travels across the desert and confronts the Preacher who does, in fact, prove to be his father, Paul Atreides. Duncan Idaho returns to Arrakis and provokes Stilgar into killing him. With Stilgar''s neutrality now untenable, he seizes Ghanima and flees. Alia recaptures Ghanima and arranges her marriage to Farad''n, planning to exploit the expected chaos when Ghanima kills him to avenge her brother''s murder. The Preacher and Leto return to the capital to confront Alia who has the Preacher murdered, revealing his true identity. Leto reveals himself in a display of superhuman strength and triggers the return of Ghanima''s genuine memories. He confronts Alia and offers to help her overcome her possession but she is overwhelmed by her ancestral personae and elects to commit suicide. Leto declares himself Emperor and asserts control over the Fremen. Farad''n enlists in his service and delivers control of the Corrino armies. The seemingly immortal and omnipotent Leto is left as Emperor of the Known Universe, with Ghanima at his side.

Children of Dune

As the novel opens, its protagonist Ragle Gumm believes that he lives in the year 1959 in a quiet American suburb. His unusual profession consists of repeatedly winning the cash prize in a local newspaper competition called, "Where Will The Little Green Man Be Next?". Gumm''s 1959 has some differences from ours: the Tucker car is in production, AM/FM radios are scarce to non-existent and Marilyn Monroe is a complete unknown. As the novel opens, strange things begin to happen to Gumm. A soft-drink stand disappears, replaced by a small slip of paper with the words "SOFT-DRINK STAND" printed on it in block letters. Intriguing little pieces of the real 1959 turn up: a magazine article on Marilyn Monroe, a telephone book with non-operational exchanges listed and radios hidden away in someone else''s house. People with no apparent connection to Gumm, including military pilots using aircraft transceivers, refer to him by name. Few other characters notice these or experience similar anomalies; the sole exception is Gumm''s supposed brother-in-law, Victor "Vic" Nielson, in whom he confides. A neighborhood woman, Mrs. Keitelbein, invites him to a Civil Defense class where he sees a model of a futuristic underground military factory. He has the unshakeable feeling he''s been inside that building many times before. Confusion gradually mounts for Gumm. His neighbor Bill Black knows far more about these events than he admits, and, observing this, begins worrying: "Suppose Ragle [Gumm] is becoming sane again?" In fact, Gumm does become sane, and the deception surrounding him (erected to protect and exploit him) begins to unravel. Gumm tries to escape the town and is turned back by kafkaesque obstructions. He sees a magazine with himself on the cover, in a military uniform, at the factory depicted in the model. He tries a second time to escape, this time with Vic, and succeeds. He learns that his idyllic town is a constructed reality designed to protect him from the frightening fact that he lives on a then-future Earth (circa 1998) that is at war with its colonists on the Moon who are fighting for a permanent Lunar habitation that is politically independent of Earth as well. Gumm has a unique ability to predict where the colonists'' nuclear strikes will be aimed. Previously Gumm did this work for the military, but then he defected to the colonists'' side and planned to secretly emigrate to the Moon. But before this could happen he began retreating into a fantasy world based largely upon the relatively idyllic surroundings of his extreme youth. He was no longer able to shoulder the awesome responsibility of being the Earth''s lone protector from Lunar-launched H-Bomb attacks. The fake town was thereby created in Gumm''s mental image to accommodate his dementia so that he would continue predicting missile strikes in the guise of submitting entries to a harmless newspaper contest and without the ethical qualms involved with being on the "wrong" side of a civil war. When Gumm finally remembers his true history he decides to emigrate to the Moon after all because he feels that exploration and migration, being as they are basic human impulses, should never be denied a people by any national or planetary government. Vic rejects this belief, referring to the colonists essentially as aggressors and terrorists, and returns to the town. The book ends with some hope for peace, because the colonists are more willing to negotiate than the Earth government has been telling its citizens.

Time out of Joint

The book''s protagonist is an English scientist and gentleman inventor living in Richmond, Surrey, identified by a narrator simply as the Time Traveller. The narrator recounts the Traveller''s lecture to his weekly dinner guests that time is simply a fourth dimension, and his demonstration of a tabletop model machine for travelling through it. He reveals that he has built a machine capable of carrying a person, and returns at dinner the following week to recount a remarkable tale, becoming the new narrator. In the new narrative, the Time Traveller tests his device with a journey that takes him to 802,701 A.D., where he meets the Eloi, a society of small, elegant, childlike adults. They live in small communities within large and futuristic yet slowly deteriorating buildings, doing no work and having a frugivorous diet. His efforts to communicate with them are hampered by their lack of curiosity or discipline, and he speculates that they are a peaceful communist society, the result of humanity conquering nature with technology, and subsequently evolving to adapt to an environment in which strength and intellect are no longer advantageous to survival. Returning to the site where he arrived, the Time Traveller is shocked to find his time machine missing, and eventually works out that it has been dragged by some unknown party into a nearby structure with heavy doors, locked from the inside, which resembles a Sphinx. Later in the dark, he is approached menacingly by the Morlocks, ape-like troglodytes who live in darkness underground and surface only at night. Within their dwellings he discovers the machinery and industry that makes the above-ground paradise possible. He alters his theory, speculating that the human race has evolved into two species: the leisured classes have become the ineffectual Eloi, and the downtrodden working classes have become the brutish light-fearing Morlocks. Deducing that the Morlocks have taken his time machine, he explores the Morlock tunnels, learning that they feed on the Eloi. His revised analysis is that their relationship is not one of lords and servants but of livestock and ranchers. The Time Traveller theorizes that intelligence is the result of and response to danger; with no real challenges facing either species, they have both lost the spirit, intelligence, and physical fitness of Man at its peak. Meanwhile, he saves an Eloi named Weena from drowning as none of the other Eloi take any notice of her plight, and they develop an innocently affectionate relationship over the course of several days. He takes Weena with him on an expedition to a distant structure that turns out to be the remains of a museum, where he finds a fresh supply of matches and fashions a crude weapon against Morlocks, whom he fears he must fight to get back his machine. He plans to take Weena back to his own time. Because the long and tiring journey back to Weena''s home is too much for them, they stop in the forest, and they are then overcome by Morlocks in the night, and Weena faints. The Traveller escapes only when a small fire he had left behind them to distract the Morlocks catches up to them as a forest fire; Weena is presumably lost in the fire, as are the Morlocks. The Morlocks use the time machine as bait to ensnare the Traveller, not understanding that he will use it to escape. He travels further ahead to roughly 30 million years from his own time. There he sees some of the last living things on a dying Earth, menacing reddish crab-like creatures slowly wandering the blood-red beaches chasing butterflies in a world covered in simple lichenous vegetation. He continues to make short jumps through time, seeing Earth''s rotation gradually cease and the sun grow larger, redder, and dimmer, and the world falling silent and freezing as the last degenerate living things die out. Overwhelmed, he returns to his laboratory, arriving just three hours after he originally left. Interrupting dinner, he relates his adventures to his disbelieving visitors, producing as evidence two strange flowers Weena had put in his pocket. The original narrator takes over and relates that he returned to the Time Traveller''s house the next day, finding him in final preparations for another journey. The Traveller promises to return in half an hour, but three years later, the narrator despairs of ever learning what became of him.

The Time Machine

The protagonist is Bob Arctor, member of a household of drug-users, who is also living a parallel life as Agent Fred, an undercover police agent assigned to spy on Arctor''s household. Arctor/Fred shields his true identity from those in the drug subculture, and from the police themselves. (The requirement that narcotics agents remain anonymous, to avoid collusion and other forms of corruption, becomes a critical plot point late in the book.) While supposedly only posing as a drug user, Arctor becomes addicted to "Substance D" (also referred to as "Slow Death," "Death," or "D"), a powerful psychoactive drug. An ongoing conflict is Arctor''s love for Donna, a drug dealer through whom he intends to identify high-level dealers of Substance D. Arctor''s persistent use of the drug causes the two hemispheres of his brain to function independently, or "compete." Through a series of drug and psychological tests, Arctor''s superiors at work discover that his addiction has made him incapable of performing his job as a narcotics agent. Donna takes Arctor to "New-Path," a rehabilitation clinic, just as Arctor begins to experience the symptoms of Substance D withdrawal. It is revealed that Donna has been a narcotics agent all along, working as part of a police operation to infiltrate New-Path and determine its funding source. Without his knowledge, Arctor has been selected to penetrate the secretive organization. As part of the rehab program, Arctor is renamed "Bruce" and forced to participate in cruel group-dynamic games intended to break the will of the patients. The story ends with Bruce working at a New-Path farming commune, where he is suffering from a serious neurocognitive deficit after withdrawing from Substance D. Although considered by his handlers to be nothing more than a walking shell of a man, "Bruce" manages to spot rows of blue flowers growing hidden among rows of corn, and realizes the blue flowers are Mors ontologica, the source of Substance D. The book ends with Bruce hiding a flower in his shoe to give to his "friends" – undercover police agents posing as recovering addicts at the Los Angeles New-Path facility – on Thanksgiving.

A Scanner Darkly

In this alternate history the corrupt US President Ferris F. Fremont (FFF for 666, ‘F’ being the 6th letter in the alphabet, see Number of the Beast) becomes Chief Executive in the late Nineteen-Sixties following Lyndon Johnson''s administration. The character is best described as an amalgam of Joseph McCarthy and Richard Nixon, who abrogates civil liberties and human rights through positing a conspiracy theory centered around a (presumably) fictitious subversive organization known as "Aramchek". In addition to this, he is associated with a right-wing populist movement called "Friends of the American People" (FAPers). Ironically enough, the President''s paranoia and opportunism lead to the establishment of a real resistance movement that is organized through narrow-beam radio transmissions from a mysterious alien near-Earth satellite, by a superintelligent, extraterrestrial, but less than omnipotent being (or network) named VALIS. As with its successor, VALIS, this novel is autobiographical. Dick himself is a major character, though fictitious protagonist Nicholas Brady serves as a vehicle for Dick''s alleged gnostic theophany on February 11, 1974. In addition, Sadassa Silvia is a character who claims that Ferris Fremont is actually a communist covert agent recruited by Sadassa''s mother when Fremont was still a teenager. As with VALIS, Radio Free Albemuth deals with author Philip Dick''s highly personal style of Christianity (or Gnosticism). It further examines the moral and ethical repercussions of informing on trusting friends for the authorities. Also prominent is Dick''s dislike of the Republican Party, satirizing Nixon''s America as a Stalinist or neo-fascist police state. Fremont eventually captures and imprisons Dick and Brady after the latter attempts to produce and distribute a record that contains subliminal messages of revolt against the current dictatorship. Brady and Silvia are executed, and Dick narrates the concluding passage about his life in a concentration camp, where his supposedly latest work is actually penned by a ghost writer and regime-approved hack. Suddenly, however, he hears music blaring from a transistor radio which contains the same subliminal message. He and his friends, it turns out, were just a decoy set up by VALIS to detour the government from stopping a much more popular A-List band from releasing a similar record with a better-established recording company. As Dick realizes this and hears youngsters repeating the lyrics he realizes that salvation may lie within the hearts and minds of the next generation.

Radio Free Albemuth

As a teenager, Mort had a personality and temperament that made him rather unsuited to the family farming business. Mort''s father, named Lezek, felt that Mort thought too much, which prevented him from achieving anything practical. Thus, Lezek took him to a local hiring fair, hoping that Mort would land an apprenticeship with some tradesman; not only would this provide a job for his son, but it would also make his son''s propensity towards thinking someone else''s problem. At the job fair, Mort at first has no luck attracting the interest of an employer. Then, just before the stroke of midnight, a man concealed in a black cloak arrives on a white horse. He says he is looking for a young man to assist him in his work and selects Mort for the job. The man turns out to be Death, and Mort is given an apprenticeship in ushering souls into the next world (though his father thinks he''s been apprenticed to an undertaker). When it is a princess'' time to die (according to a preconceived reality), Mort, instead of ushering her soul, saves her from death, dramatically altering a part of the Discworld''s reality. However, the princess, for whom Mort has a developing infatuation, does not have long to live, and he must try to save her, once again, from a seemingly unstoppable death. Both the princess and Mort end up consulting the local wizard, Igneous Cutwell, for various methods of assistance with the crisis. As Mort begins to do most of Death''s "Duty", he loses some of his former character traits, and essentially starts to become more like Death himself. Death, in turn, yearns to relish what being human is truly like and travels to Ankh-Morpork to indulge in new experiences and attempt to feel real human emotion. Conclusively, Mort must duel Death for Mort''s freedom. Though Death wins the duel, he spares Mort''s life and sends him back to the Disc. The princess is saved from a second death when the alternate reality Mort created is reduced to a pearl-like state. This pearl is given to Mort for safe-keeping. At the end of the novel, Mort marries Ysabell, Death''s adopted daughter.

Mort

A Malthusian catastrophe on Earth has been averted by the invention of teleportation, called the "Ramsbotham jump", which is used to send Earth''s excess population to colonize other planets. However, the costs of operating the device mean that the colonies are isolated from Earth until they can justify two-way travel. Because modern technology requires a supporting infrastructure, more primitive methods are employed — for example, horses instead of tractors (because tractors cannot reproduce themselves). Rod Walker is a high school student who dreams of becoming a professional colonist. The final test of his Advanced Survival class is to stay alive on an unfamiliar planet for between two and ten days. Students may team up and equip themselves with whatever gear they can carry, but are otherwise completely on their own. They are told only that the challenges are neither insurmountable nor unreasonable. On test day, each student walks through the Ramsbotham portal and finds him or herself alone on a strange planet, though reasonably close to the pickup point. Rod, acting on advice, chooses to equip himself with hunting knives and basic survival gear rather than high-tech weaponry, on the grounds that the latter is dependent on the infrastructure required to maintain it and can easily become a crutch. The last advice the students receive is to "watch out for stobor." On the second day, Rod is ambushed and knocked unconscious by a thief. When he wakes up, all he has left is a spare knife hidden under a bandage. In his desperate concentration on survival, he loses track of time. Eventually he teams up with Jacqueline "Jack" Daudet, a student from another class whom he initially mistakes for a male. When she tells him that more than ten days have elapsed without contact, he realizes that they are stranded. They start recruiting others for the long haul and Rod becomes the de facto leader of a community that eventually grows to around 75 people. Rod has no taste for politics or administration, and is happy to have Grant Cowper, an older college student and born politician, elected "mayor". Grant proves to be much better at talking than getting things done. Despite disagreeing with many of Grant''s policies, Rod supports him. Grant ignores Rod''s warning that they are living in a dangerously hard-to-defend location and that they should move to a cave system he has found. When a species previously thought harmless suddenly changes its behavior and stampedes through their camp, the settlement is devastated and Grant is killed. Rod is subsequently put back in charge. Heinlein tracks the social development of this community of educated Westerners deprived of technology, followed by its abrupt dissolution when contact with Earth is reestablished. After nearly two years of isolation, the culture shock experienced by the survivors highlights for them, and the reader, the pain and uncertainty of becoming an adult, by reversing the process abruptly -- Each of the students goes from being a personally self-responsible member of an autonomous community back to being a youth with little authority or responsibility in the home culture. All of the students go back willingly except for Rod, who has great difficulty reverting from the status of head of a small, but sovereign state to a teenager casually brushed aside by the adult rescuers. However, his teacher (and now brother-in-law) and his sister persuade him to change his mind. His teacher also informs Rod that his warning against "stobor" ("robots" spelled backwards) was just a way of personalizing the dangers of an unknown planet - to instill fear and caution in the students. Years later, Rod is briefly depicted accomplishing his heart''s desire; the novel''s ending finds him preparing to lead a formal colonization party to another planet.

Tunnel in the Sky

In the 22nd century, Dr Vannevar Morgan is a famous structural engineer who hopes to develop the ''space elevator'' from a theoretical concept to reality and enlists the resources of his employers to carry out experiments. But the only suitable starting point (Earth station) for the elevator lies at the summit of a mountain in Taprobane occupied by an ancient order of Buddhist monks, who implacably oppose the plan. Morgan is approached by a Mars-based consortium to develop the elevator on Mars as part of a massive terraforming project. To demonstrate the viability of the technology, Morgan tries to run a thin cable of ‘hyperfilament’ from an orbital factory down to ground level at Taprobane. A monk at the monastery, a former astrophysicist who is a mathematical genius, tries to sabotage the attempt by creating an artificial hurricane using a hijacked weather-control satellite. His attempt is in fact successful, but in an ironic twist, the hurricane blows butterflies to the peak of the mountain. This fulfills an ancient prophecy that causes the monks to leave the mountain. The tower can be built on Earth after all. Forced to resign his position for acting beyond his authority, Morgan joins the Martian consortium named ''Astroengineering'' and construction of the Tower commences. Several years later, the Earth-based tower is well under construction and travel up and down &mdash; both for tourists and for transfer to rocket ships &mdash; is being trialled. An astrophysicist and a group of his students and tower staff are stranded in an emergency chamber six hundred kilometres up after an accident with their transport capsule. They have limited food and air supplies. Whilst a laser on a weather-control satellite is able to supply heat, it is imperative to provide them with filter masks against the increasing carbon dioxide and also with food, air, and medical supplies (a theme earlier explored in Clarke''s novel The Sands of Mars). Despite his rapidly failing health, Morgan asserts his right to travel up the tower in a one-man ''spider'' to rescue them. He nearly fails, with limited battery power, but ultimately succeeds in reaching the chamber. As Morgan surveys the progress of his brainchild, his heart disease claims his life. A short epilogue envisages Earth many centuries later, after the sun has cooled and Earth has been depopulated, with humans now living on the terraformed inner planets. Several space elevators lead to a giant "circumterran" space station that encircles Earth at geostationary altitude. The analogy with a wheel is evident: the space station itself is the wheel rim, Earth is the axle, and the six equidistant space elevators the spokes.

The Fountains of Paradise

The book covers several periods from the life of Lazarus Long (birth name: Woodrow Wilson Smith), the oldest living human, now more than two thousand years old. The first half of the book takes the form of several novellas connected by Lazarus''s retrospective narrative. In the framing story, Lazarus has decided that life is no longer worth living, but (in what is described as a reverse Arabian Nights scenario) will consent not to end his life as long as his companions will listen to his stories. This story concerns a 20th century United States Navy cadet who rises in the ranks while avoiding any semblance of real work by applying himself wholeheartedly to the principle of "constructive laziness". After the Naval Academy, the protagonist becomes rich by taking advantage of the Agricultural Adjustment Act, which paid farmers not to farm their land. Lazarus tells of his visit as an interplanetary cargo trader to a planet with a culture like that of the medieval Middle East (reminiscent of Citizen of the Galaxy), whereon he bought a pair of slaves, brother and sister, and immediately manumitted them. Because neither has any knowledge of independence, nor any education, Lazarus teaches them during the voyage "how to be human". The two are the result of an experiment in genetic recombination in which two parent cells were separated into complementary haploid gametes, and recombined into two embryos. The resulting zygotes were implanted in a woman and gestated by her, with the result that although both have the same mother and genetic parents, they are no more closely related genetically than any two people taken at random. They have been prevented from sexual relations by a chastity belt; but having confirmed that there is no risk of genetic disease in their offspring (described as the sole valid reason against incest), Lazarus solemnizes their marriage and later establishes them as the owners and operators of a thriving business. At the end of the story, he reveals a belief that they are descendants of his own. A short scene-setter written after the style of "The Song of Hiawatha" introduces a planet whereto Lazarus has led a group of colonists now living in a manner reminiscent of the American Old West. Lazarus, now working as a banker and shopkeeper and keeping his true age secret, saves a young girl named Dora from a burning building and becomes her guardian. When she grows up, he marries her, and the two become founders of a new settlement where Lazarus'' long life is less likely to be noticed. They are successful and eventually build a thriving town. Because Dora is not a Howard Family member, she eventually dies of old age, leaving Lazarus to mourn her loss. At the beginning of this story, Lazarus has regained his enthusiasm for life, and the remainder of the book is told in a conventional linear manner. Accompanied by some of his descendants, Lazarus has now moved to a new planet and established a polyamorous family consisting of three men, three women, and a larger number of children, two of whom are female clones of Lazarus himself. In the concluding tale, Lazarus, in a quest to experience something "new", attempts to travel backward in time to 1919 in order to experience it as an adult; but an error in calculation places Lazarus in 1916 on the eve of America''s involvement in World War I. An unintentional result is that Lazarus falls in love with his own mother. In order to retain her esteem and that of his grandfather, Lazarus enlists in the army. Eventually Lazarus and his mother, Maureen, consummate their mutual attraction before Lazarus leaves for France. While in France, he is mortally wounded in the trenches of the Western Front, but rescued by those with whom he appears in Boondock and returned to his own time. There are also two "Intermission" sections, each some six or eight pages long, taking the form of lists of provocative phrases and aphorisms not directly related to the main narrative. These were later published independently, with illustrations, as The Notebooks of Lazarus Long.

Time Enough for Love

The novel is set in a future a few decades ahead of the 1960s, when it was written. The USA is still competing with the Soviet Union. Both have functioning bases on the Moon, and the Soviets have gained the lead in sending an expedition to Mars. From the point of view of most of the population of the Earth, a new planet appears out of nothing close to the Moon, shortly after a total lunar eclipse. Over a period of few days the planet appears to consume the Moon. On Earth, the new planet''s gravity causes death and destruction as it raises huge ocean tides and causes earthquakes and volcanic eruptions. Flying saucers appear in the skies, apparently trying to mitigate some of the disastrous effects. Then after a spectacular battle in space between the new planet and another, the skies are empty again. Earth is left without a Moon. The novel follows the lives of people around the globe. There is a man attempting a solo crossing of the Atlantic ocean, a smuggler operating off the coast of Vietnam, two friends in England, a trio of drug addicts in New York City, and the military controllers of the USA Moon mission, deep in a bunker somewhere near Washington DC. The new planet is referred to by everybody as simply "the Wanderer". The main protagonists are three longtime friends. Paul Hagbolt is escorting Margo Gelhorn (and her cat, Miaow) to observe the lunar eclipse at an observatory in California. Their friend, and Margo''s fiance, is Don Merriam, one of the American astronauts at the Moon base. Following on a whim a sign advertising a "flying saucer symposium", Paul and Margo fall in with a group of intellectuals, dreamers, charlatans and misfits. At that point events overtake them. The new planet appears and triggers an earthquake that buries their cars in a landslide. They must avoid tsunamis, more earthquakes, roving mobs and flying saucers to survive. On the Moon Don Merriam is the only one to escape the destruction of the moonbase. He tries to take off in one of the base''s spaceships, only to fall through the Moon itself as it splits into two under the influence of the new planet. His ship is eventually captured by the inhabitants of the new planet. Events take a bizarre turn when the group of saucer enthusiasts is faced with a tsunami. A flying saucer appears, and a cat-like being uses some kind of gun to repel the waves. Then the being uses the same device to pull Paul, who is holding Miaow, into the saucer. At the same time the gun falls into the hands of the people on the ground. In the saucer Paul meets a being calling itself Tigerishka. A large, female telepathic feline creature, she initially mistakes Miaow as the intelligent being whose thoughts she can hear, and Paul as a "monkey". Realizing her mistake, she regards Paul with contempt. Monkey-beings are not well regarded by her people. However she slowly warms to him, and explains why her planet has appeared to consume the moon. Like many of the human characters, her people are intellectuals, dreamers, charlatans and misfits. They belong to a culture that spans the Universe, has achieved immortality, and can construct planets and traverse hyperspace. They can create bodies for themselves that reflect the origins of their races, such as Tigerishka''s cat-form. However they are fleeing their culture''s police. Their culture rejects nonconformists, instead devoting itself to ensuring that intelligent life survives to the end of time. Tigerishka''s people want to explore hyperspace, and tinker with space, time and the Mind. Their flight has brought them to Earth orbit simply to refuel. Huge amounts of matter must be converted to energy to power their hyperspace drive and their weapons. As alien as Tigerishka is, Paul becomes besotted with her. Tigerishka eventually yields to his advances. At the same time, Don Merriam has been rescued with his ship by the Wanderer''s other spaceships. He is reunited with Paul aboard Tigerishka''s ship. Now they must testify in the Wanderer''s trial, for the police have arrived. A second planet, "The Stranger", colored a dull gray where the Wanderer is bright purple and yellow, appears and threatens battle. Don and Paul give their testimony as to the good treatment they have seen, along with thousands of other humans appearing by some kind of holographic projection. However the trial goes badly. Paul and Don are evacuated in Don''s ship, placed into position close to Earth by Tigerishka. Tigerishka takes Miaow with her back to her planet. Then the final battle takes place, and both planets disappear. In the final scene, Margo and her companions walk to Vandenberg Spaceport as Don''s ship comes in to land.
