''Eight Worlds'' is a loosely coupled (and not particularly consistent) ScienceFiction series by Creator/JohnVarley. It consists of several novels and a number of short stories.

The basic premise is that in the not-too-distant future, as humanity is starting to settle other planets in the solar system, some SufficientlyAdvancedAliens come along and simply banish humans from Earth, without even an attempt at communication, let alone negotiation. Without access to Earth, humanity is forced to get along, as best it can, with the eight settled planets and moons of the system. Cut off from its cultural roots, society quickly grows in new and unexpected ways.

Novels in the series include ''The Ophiuchi Hotline'', ''Steel Beach'', and ''The Golden Globe''. ''Steel Beach'' was nominated for a HugoAward in 1993. The 1979 short story, "Overdrawn at the Memory Bank", was made into a [[Film/OverdrawnAtTheMemoryBank Made-For-TV movie]].
----
!! This series contains examples of:
* AIIsACrapShoot:
** In ''Steel Beach'' "CC", the lunar Central Computer, has grown beyond human comprehension, and it's hurting. Which could be a problem, considering it's literally linked to everything, including the human population themselves through their various implants.
** In ''The Golden Globe'' Sparky uses an assassin's severed thumb to hijack his spaceship, only to find out that the ship's AI saw right through his ruse but went along with the hijacking anyway because it thought Sparky would make a more interesting passenger than the assassin.
* AllJustADream: Invoked in ''Steel Beach'', when the protagonist is kept in an artificially induced dream for therapeutic purposes--something he's not happy about when he figures it out.
* AnythingThatMoves: In ''The Golden Globe'', there's a drug that inflicts this. It's banned because male recipients have [[DeathBySex electrocuted themselves attempting to couple with light sockets.]] It's administered to [[EveryoneIsBi a rare straight character]] so that he'll sleep with his [[VoluntaryShapeshifting technically]] [[GenderBender male]] fellow actor playing Juliet. This performance only, Romeo attempts to hump Friar Laurence's leg! ItMakesSenseInContext.
* ArtificialMeat: The heroine of ''The Ophiuchi Hotline'' gets wealthy from developing a "bananameat" tree. Ostensibly the grafting of pork genes onto banana trees, the popularity of the meat's flavor is the result of including human DNA (the inventor's own).
* AttractiveBentGender: In ''Steel Beach'', protagonist Hildy Johnson starts out as a fairly standard looking male but, [[EasySexChange after a high tech sex-change]] (a common motif in Varley's work), becomes a stunning woman. Unlike most examples of this, with Hildy it's intentional -- he/she doesn't care what he looks like as a man but wants to be the most attractive woman she can be (plus the body artist owes her a favor).
* {{Asexual}} a recognized orientation bound to be mentioned any time Varley introduces a character without apparent genitals. For example, Hildy briefly wonders what her apprentice Brenda's lack of genitalia implies before concluding that it's none of her business. Boss Tweed, a character in Opiuchi Hotline who actually is asexual, retains false genitalia specifically to head off this sort of speculation.
* AsteroidMiners: In ''The Ophiuchi Hotline'', there are ''Oort Cloud'' miners in the outermost regions of the solar system, hunting for micro-black holes.
* BatmanCanBreatheInSpace: People are often fitted with a portable force-field generator which operates automatically when they walk from pressurised to unpressurised areas. The force-fields merge when brought together so that people can embrace and even make love in vacuum. Meanwhile, in the rings of Saturn, the Symbs are humans who live in symbiosis with biological, semi-sentient spacesuits. They spend their entire lives in vacuum, the symbiotes providing them with all the oxygen they need and recycling their waste for nutrition via photosynthesis.
* BiggerIsBetterInBed: Averted/Discussed. After her first session with a new love interest, the heroine of ''Steel Beach'' specifically references this trope when she bitches [[IncrediblyLamePun at length]] about the tendency of first time Female-to-Male {{gender bender}}s to check off the "HUNG" option even though they'd just been girls themselves and really ought to know better.
* BodyBackupDrive: The technology exists to make a copy of a person's memories, and to grow a clone from a tissue sample. Life insurance now consists of going in for annual (or more often, if you can afford it) backups of your memories, and if you get killed, your insurance company grows a clone, and loads your memories into it. Having more than one of you running around at once is very illegal, however, and any extra clones discovered are subject to summary destruction. This allows at least one unscrupulous character to create slaves with no rights or recourse, since their very existence is a crime.
* ButWhatAboutTheAstronauts: more-or-less the premise of the whole series, if you substitute "colonists" for "astronauts".
* CloningBlues: For a while, there is a law that only one person can own a genotype: all copies must be destroyed. So if you discover that you're an illegal clone, your only hope is to kill your progenitor and replace him/her. Cue several plots.
* ConjoinedTwins: Briefly mentioned: a passing fad for voluntary conjoinment among jaded thrill-seekers.
* EasySexChange: Sex changes are so commonplace that anyone who spends their entire life without changing at least once is considered a little weird and population control laws are basically: "one person, one child."
* EveryoneIsBi: three protagonists, three different takes on this:
** ''Steel Beach'' You can be any sex you want. You can be any shape you want. You can live as long as you want, barring terminal ennui. You're actually gonna tell me you're not willing to try everything at least once?
** ''The Golden Globe'': You're an actor in a FreeLoveFuture that demands sex scenes in Shakespeare and even children's educational television. Pickyness is NOT a viable career option.
** ''The Opiuchi Hotline'': Having a partner who is attentive to your needs is more important than their nominal (or in some cases, purely notational) gender.
* ExoticEquipment:
** In ''The Ophiuchi Hotline'', the heroine dismisses a potential suitor because he'd had his penis radically modified to fit the latest fetish/fad (he protests that it [[MaleToFemaleUniversalAdaptor came with an adapter]]) and another character who'd gone in for much more radical body modifications is credited for a very creative solution to the question of where a crotchless woman would keep her genitals. In both cases Varley (perhaps wisely) left the actual details to the reader's imagination.
** In ''Steel Beach'': Opening line: "'In five years, the penis will be obsolete' said the salesman." This subsequent pitch is mostly ignored by the protagonist, since exotic replacement equipment is so mundane advertisers announce the "sexual millenium" on a regular basis.
* ExpendableClone: The hero of ''The Golden Globe'' -- an unknowing clone -- gets away with killing his own "father" on a technicality due to a now-obsolete anti-cloning law that prohibited two people from sharing identical DNA. Fortunately for him the law didn't actually specify which clone had to be killed.
* {{Fingore}}: In ''The Golden Globe'', Sparky slices off the thumb of an assassin who is after him. With a chainsaw. He keeps it in a thermos of dry ice. This might be partly revenge for the fact that the assassin had sliced off the fingers of a violinist friend of his, but Sparky's primary intent is to use it to defeat the biometric lock on the assassin's spaceship.
* FormerChildStar: Kenneth Valentine of ''The Golden Globe'' is a seriously messed-up example, although, unlike the classic version, he's trying to hide from his past rather than wishing he could relive his glory days. He's actually a first-rate actor, but he avoids taking major roles because he doesn't want people to make the connection between him and "Sparky" (the role that made him famous as a kid) Of course, the fact that he also happens to be wanted for murder might have something to do with it.
* FossilRevival: Brontosaurs have been brought back, and serve as common food animals on Luna. Hildy, the protagonist of ''Steel Beach'' is the child of a brontosaur farmer.
* FreeLoveFuture: With gender-changes so commonplace, and even ExoticEquipment options available to all, traditional mores are hard-pressed to keep up. Though, of course, some traditionalists do still prefer the old ways. Varley does not shrink from exploring the positive and the negative implications.
* GenderBlenderName: Much more common now that EasySexChange is both available and commonplace, though many just change names when they change sexes.
* GlorifiedSpermDonor: Used twice in ''Steel Beach'' when Hildy refuses to inform her baby's father that she's pregnant even though her own mother's constant refusal to identify ''her'' father causes her considerable angst. [[spoiler: After the baby dies her reasoning shifts from a selfish "mine, all mine" to "why ruin his [the father's] day?"]]
* ImaginaryFriend: In ''The Golden Globe'', protagonist Kenneth "Sparky" Valentine's imaginary friend turns out to be a symptom of a disassociative personality disorder caused by years of suffering at the hands of his abusive father, Kenneth Sr.
* IndividualityIsIllegal: In the short story "[[Literature/EightWorlds The Barbie Murders]]", investigators are hard-pressed to investigate a murder in a colony of "Conformists", all of whom are surgically altered to look exactly the same, including the complete removal of genitalia (thus nicknamed "Barbies") and who all receive news simultaneously, not distinguishing between themselves ("this body") and others. Individualists within the colony are seen as outsiders at best (as with the investigators) and perverts at worst (as with the murder victim, who was a converted Barbie who still engaged in individualist practices).
* InscrutableAliens: Those which banished everybody from Earth.
* InsideAComputerSystem:
** ''OverdrawnAtTheMemoryBank'' (and its infamous film adaptation) has a man whose consciousness is loaded into a computer to keep him alive after his body is misplaced.
** ''Steel Beach'' has the protagonist spend several virtual years (and very little actual time) inside a therapeutic computer simulation.
* MaleToFemaleUniversalAdaptor:
** ''Steel Beach'' has the ULTRA tingle system, which gets around the whole genital compatibility issue entirely by using wireless modems for sex.
** [[TheProtagonist The actor protagonist]] of ''The Golden Globe'' equipped himself with a penis that can be turned inside out for use as a vagina, primarily because it doubles his chances of getting roles.
** Finally, ''The Opiuchi Hotline'' has literal [[MaleToFemaleUniversalAdaptor male to female universal adaptors]] that allow characters who go in for radically modified genitals to "dally" with their more conservative counterparts.
* MermaidProblem:
** In ''The Golden Globe'' a theatrical director in the far future complains about the difficulty of finding actresses willing to give up sex in order to play mermaids; it seems far future labor laws have replaced CGI with MagicPlasticSurgery.
** One character in ''The Opiuchi Hotline'' is a spacer who has used MagicPlasticSurgery to [[{{Transhuman}} modify her body until she's literally just a cylinder with an arm on each end.]] Varley's protagonist gives her credit for coming up with a very creative solution for the question of where a crotchless woman would keep her genitals but Varley (perhaps wisely) [[FetishFuel doesn't specify what that solution was.]]
* NightmareFetishist: An entire society of Nightmare Fetishists, the Charonese, though how much of that is hype isn't entirely clear.
* NoBiologicalSex: Comes along with the EasySexChange; some people prefer to opt out of the game completely, either temporarily or permanently. One character describes it as a "vacation from sexuality."
* NoDeadBodyPoops: An impressive aversion in ''Steel Beach'': we learn that low gravity + explosive decompression + no space suits/clothing (clothing optional moon colony) + bowel gas = the 'Brown Rocket' effect.
* NoNudityTaboo: more due to obsolescence (sealed environments) than anything else.
* NotAllowedToGrowUp: Kenneth "Sparky" Valentine, the narrator of ''The Golden Globe'' is an actor who played the same child role for ''decades''.
* OfCorsetsSexy: In ''Steel Beach'', Hildy adopts corsets when she moves into a Victorian-era historical reenactment community (even though period underwear is not required) on the theory that anything worth doing is worth doing right. She freely admits the titillation factor played a significant role in her decision.
* OrionDrive:
** ''Steel Beach'' sets several scenes near or within the bulk of the "Robert A. Heinlein," an Orion-style ship which was built and then abandoned when humanity lapsed into apathy for stellar exploration.
** At the end of ''The Golden Globe'', the "Heinleiners" (radical libertarians) finish refitting the Heinlein and head out for the stars.
* OurNudityIsDifferent: Hildy points out that even though nudity is entirely practical in Luna's artificial environments most people still wear some clothing, primarily as a means of personal expression. At least One cult ("The Barbies") rejects clothing entirely exactly because it is a means of personal expression.
* OutgrownSuchSillySuperstitions: Played with. Getting kicked off of earth by alien invaders pretty much put the kibosh on most traditional human-centric religions, but people just went on to create a bunch of new religions anyway, including ones that worship the invaders, gluttony, or, in the case of the flacks, fame.
* PlanetOfHats: The short story "The Barbie Murders" features a cult of humans nicknamed "The Barbies" who are obsessed with conformity. They have each been modified to look and sound identical, down to the last tiny detail, including the removal of their genitalia. They have no names or personal identities, and each takes responsibility for the actions of all the rest. This makes finding a murderer in their midst rather trying.
* PornWithPlot: Parodied in ''The Golden Globe'', where the audience expects graphic sex scenes in all media, leading to the actor protagonist performing a very... interesting... version of the balcony scene from Shakespeare's ''Romeo and Juliet''.
* {{Robinsonade}}: In ''Steel Beach'' the protagonist inexplicably spends an entire chapter in an Robinson Crusoe setting. It turns out to be [[spoiler:a set of fictitious memories implanted by the AI overseeing everything as an experimental therapy as it works to develop a response for a disturbing increase in certain psychological disorders e.g. suicidal depression. CC does it to Hildy again later, only this time using a combination visual novel/adventure game scenario intended for children.]]
* SecondLawOfGenderBending: rendered irrelevant by EasySexChange.
* SpaceAmish: ''The Golden Globe'' includes genuine Amish living on the moon, who befriend Sparky at one point. They are just like the real Amish in that they are they are neither ignorant of nor resistant to the modern world surrounding them, they're just very particular about which aspects of that world they choose to accept.
* SteelEardrums: In the short story "In the Bowl", one of the main characters laments that since they were going on a trip with well known exploding crystals in the area, they were foolish to forget to pack extra ear drums.
* TheSymbiote: Artificially cultured plant-based organisms that are bonded with humans to produce a single organism that has it's own individual animal/plant ecology. They don't breathe or eat, and spend their time in open space, usually touring the rings of Saturn. One named Parameter/Solstice is an important character in ''The Ophiuchi Hotline''.
* TellMeAboutMyFather: Subverted in ''Steel Beach'' as Hildy's mother flatly refuses to even identify her father, let alone tell her anything about him. The resulting animosity causes periodic breaks in their relationship, But that doesn't prevent Hildy from resolving to similarly conceal the father's identity from her own child Mario.
* TerminallyDependentSociety: Without access to Earth, society is fragile and very dependent on technology. In ''Steel Beach'', when the Central Computer (CC) [[AIIsACrapshoot goes insane]], they realize just how dependent they are.
* ThirdLawOfGenderBending: Despite being a serial GenderBender herself, Hildy Johnson, in ''Steel Beach'', insists that there are still "girl things" and "boy things" when it comes to dress and behavior, because otherwise there would be little point in changing gender in the first place. This serves to underscore that EasySexChange has become so easy in Hildy's world (you can get a sex change in a beauty shop or a tattoo parlor) that some people are willing to change sex just to facilitate a relationship or even just to suit their clothes.
* {{Transhuman}}: The series is filled with transhumanism. Even though human genetic experimentation is technically illegal there's always surgery, symbionts, cybernetics and nanotechnology so it's not unusual for people to modify their bodies (sometimes radically) to suit a specific environment, fad, fetish, or job. While the people who go for the most radical physical modifications tend to be professional spacers (who tend to discard things like legs and feet that are not very useful in zero gravity) most people are so cyberized the lunar central computer admits to tapping the unused portions of their brains for additional processing power. In ''The Opiuchi Hotline'' society has become so fluid that the very concept of humanity is breaking down even as aliens who are even further along that path offer to adopt "human" as their cultural identity since they've lost nearly all semblance of their own.
* Transexual: common via EasySexChange.
* TrulySingleParent: although it's technically illegal, it's a recurring theme:
** In ''The Ophiuchi Hotline'', Lilo is one many times over.
** In ''The Golden Globe'', the protagonist, Sparky Valentine, discovers he's a clone of his father.
* UnreliableCanon: The novels in the series frequently contradict each other when it comes to matters that could be called canon. Varley has admitted that he doesn't like going back to re-read his old works, and doesn't really care about the overall canon.
* UnreliableNarrator: Hildy Johnson and Sparky Valentine, though to different degrees. Sparky because of the disassociative personality disorder stemming from his abusive childhood, and Hildy because she's a jaded and cynical tabloid reporter who isn't always willing to accept the truth about herself.
* WeWillNotHavePocketsInTheFuture: Averted. According to Hildy, pockets are a major reason people still bother to wear clothes.
* WhodunnitToMe: The short story, "The Phantom of Kansas", opens with the protagonist awakening and discovering that this is the ''third'' time she's been restored from backup. The original, and the two previous backups, have all been killed.
* WhoWantsToLiveForever: People may all be potentially immortal (due to really advanced medical technology), but very few of them actually live much beyond 300 years, largely due to the effects of this trope.
* WritingAroundTrademarks: ''The Barbie Murders, and Other Stories'' was re-released as ''Picnic on Nearside'' (another short story in the collection) after Mattel objected to the book title.
* YouDoNOTWantToKnow: ''The Golden Globe'' averts ForbiddenFruit in this regard: to show that you don't want to know how Charonians have sex, you're given a description of their coming-of-age ceremony. For context, Charonians [[GoodThingYouCanHeal regenerate quickly]] and worship pain, and the ceremony itself is either {{Narm}} or NauseaFuel, though it's unclear how much of that is truth and how much of it is Charonese propaganda.
