There is a science that reads the future of quadrillions the way an astronomer reads the orbits of stars. It is called psychohistory, and its equations foresee something the ruling Galactic Empire cannot admit: the throne is rotting, and thirty thousand years of barbarism are coming. One man, Hari Seldon, cannot stop the fall. He can only shorten it — by seeding a Foundation of scholars at the rim of the galaxy, a fragile institution built to carry knowledge across the dark and cut the interregnum to a single millennium. This is a universe told in the register of history itself: the long view, the calm of deep time, empires measured in centuries and men measured against them. The spine is Asimov's original trilogy — Foundation, Foundation and Empire, Second Foundation — followed decades later by the sequels Foundation's Edge and Foundation and Earth and the prequels Prelude to Foundation and Forward the Foundation. Late in life Asimov braided this in with his other future histories: the Robot novels of detective Elijah Baley and his humaniform partner R. Daneel Olivaw (The Caves of Steel, The Naked Sun, The Robots of Dawn, Robots and Empire) and the early Galactic Empire novels (Pebble in the Sky and its kin), until one continuous chronicle ran from the first thinking robots to the Second Empire. Other hands extend it — the Second Foundation Trilogy by Gregory Benford, Greg Bear, and David Brin, and shared-world spinoffs such as Robot City — so the corpus sprawls beyond a single author's tidy shelf. What distinguishes it is that the drama is intellectual: crises resolved by insight, nerve, and dialogue rather than fleets and blades, each turn hinging on the hidden logic of the Seldon Plan. Begin where readers have always begun — with Foundation, and the original trilogy in publication order. The rest opens outward from there.

Orson Scott Card's Ender's Game (1985, expanded from his 1977 novella) follows child prodigy Andrew "Ender" Wiggin as he is recruited into a military training program built to prepare Earth's defenses for an anticipated third war against an insectoid alien species known as the Formics. The saga continues years later through Speaker for the Dead and Xenocide, following an older Ender as he confronts the moral weight of his role in that earlier conflict, and concludes the core arc in Children of the Mind, with Ender in Exile filling in the years between the first two books. Set within the wider Ender's Game universe, the series shifts from military coming-of-age story to slower, more philosophical science fiction as it progresses.

Somewhere a blue police box that has no business existing folds a whole world in behind one door, and an old traveller wearing a brand-new face steps out onto a beach, a battlefield, the last warm afternoon of a dying sun. The Whoniverse is all of time and space and the wanderer who refuses to sit still inside it — the Doctor, who dies only to change shape and carry on, gathering friends across every century and losing rather more of them than the adventures like to admit. It runs on curiosity, mercy, and the unshakeable conviction that no one small should be left to the monsters. On the page it is vast and gloriously many-handed. It begins with the Target novelizations, pocket retellings of the television serials — Terrance Dicks alone wrote scores of them — that taught a generation to hear the show in prose. When the screen went dark the books carried the story on: the Virgin New Adventures walked the Seventh Doctor into darker, stranger country and gave the world the archaeologist Bernice Summerfield; BBC Books answered with ranges for the Eighth Doctor and every past incarnation, before the 2005 revival brought the New Series Adventures. Around the edges cluster the spin-offs — Bernice's own long saga, Paul Magrs's gin-soaked interdimensional diva Iris Wildthyme, the pharaoh-companion Erimem, the grown-up Cardiff shadows of Torchwood — steered across decades by hands like Justin Richards and Stephen Cole. Nothing here demands to be read in order, and that is rather the point: it is a world you drop into, not a staircase you climb. The register shifts with every author and every Doctor — high adventure, cosmic dread, farce, elegy, sometimes inside one book — bound together only by that restless kindness. Begin with the Doctor you already half-remember: a Target novelization of a favourite serial, or a New Series Adventure for whichever face first caught you. Then just leave the door open.

One night, the stars vanish behind an opaque membrane that has sealed off the Earth, and inside it time runs so much slower than the universe outside that billions of years pass beyond the barrier for every year lived on the ground. Robert Charles Wilson's Spin follows three friends who grow up in the shadow of this event, as humanity scrambles to understand and survive it through desperate projects like terraforming Mars, while trying to make contact with the ancient machine intelligences responsible, the Hypotheticals. The trilogy continues in Axis and Vortex, widening the mystery across generations.

The Culture series is a science fiction series written by Scottish author Iain M. Banks and released from 1987 until 2012. The stories centre on The Culture, a utopian, post-scarcity space society of humanoid aliens and advanced superintelligent artificial intelligences living in artificial habitats spread across the Milky Way galaxy. The main themes of the series are the dilemmas that an idealistic, more-advanced civilization faces in dealing with smaller, less-advanced civilizations that do not share its ideals, and whose behaviour it sometimes finds barbaric. In some of the stories, action takes place mainly in non-Culture environments, and the leading characters are often on the fringes of the Culture, sometimes acting as agents of the Culture in its plans to civilize the galaxy. Each novel is a self-contained story with new characters, although reference is occasionally made to the events of previous novels.

Chocky (1968) is John Wyndham's science fiction novel about an eleven-year-old boy, Matthew, whose parents grow alarmed by his conversations with an unseen presence that feeds him unsettling insights into mathematics and human progress, building toward the reveal of what, or who, Chocky really is. Mark Daniel's Chocky's Challenge (1986), published after Wyndham's death, is an authorized continuation that carries the story forward.

The Gaea Trilogy consists of three science fiction novels by John Varley. The stories tell of humanity's encounter with a living being in the shape of a 1,300 km diameter Stanford torus, inhabited by many different species, most notably the centaur-like Titanides, in orbit around the planet Saturn.

The Time Traders opens Andre Norton's Cold War-flavored science fiction series, following an American agent recruited to travel into the past and counter a Soviet operation built around ancient technology unearthed from a vanished civilization. Norton, later joined by collaborators Sherwood Smith and P. M. Griffin, expanded the sequence to seven novels published between 1958 and 2002, and revised the opening book herself in 2000. Like several of Norton's other series, it treats leftover technology from a long-gone ancient culture as its central plot engine.

Dangerous Visions (1967), Again, Dangerous Visions (1972), and the posthumously finished The Last Dangerous Visions (2024) are Harlan Ellison's landmark science fiction anthologies of original, previously unpublished stories, each conceived to push past the genre's conventional boundaries of its time. Ellison edited and introduced all three, though his death in 2018 left the final volume to be completed and published by others years later. The three books form a loosely connected set of era-defining anthologies spanning nearly six decades rather than a continuous story.

H. G. Wells's 1901 novel The First Men in the Moon is narrated by the businessman Bedford, who joins the reclusive scientist Cavor after Cavor invents cavorite, a gravity-blocking substance that carries the two men to the Moon.
