Mood

The mood the book leaves you in.

  • The reading experience is propelled by journeys, exploration, and physical risk; excitement and forward momentum dominate over dread or introspection.
  • Joy and loss are deliberately mixed; the resolution grants characters something real while taking something else away, leaving warmth and sorrow together.
  • The book demands work from the reader — dense prose, difficult structure, unfamiliar ideas, or morally uncomfortable material — as part of its intended effect.
  • Grim events, cruelty, or despair dominate the atmosphere, and the book does not soften them with comfort or comic relief.
  • The atmosphere is quietly unsettling — wrongness, unease, and the uncanny pervade the book without necessarily escalating into overt horror.
  • The book is built to move the reader; character feeling is foregrounded and major scenes aim at a strong emotional response.
  • Humor is a primary aim and the prose plays for laughs — comic situations, wit, or dialogue produce sustained comedy, not occasional levity.
  • The book insists that things can improve; effort and decency are shown to matter, and the arc bends toward better outcomes even through hardship.
  • The book teaches as it goes — real facts, history, science, or craft are conveyed in enough depth that learning is part of the reading experience.
  • The book is designed to uplift and motivate, presenting perseverance or achievement in a way that invites the reader to aspire or act.
  • The overall register is cheerful and easygoing; stakes are kept gentle and the book avoids dwelling on pain or dread.
  • Withheld information drives the experience; the book sustains enigmas and secrets the reader wants resolved, whatever its genre.
  • The book is contemplative and inward-looking, giving more weight to thought, memory, and meaning than to external events.
  • Grief, loss, or melancholy set the dominant register, and the book lets sorrow stand rather than resolving it into comfort.
  • Sustained suspense is the point; the book keeps the reader braced for what happens next through danger, pressure, or impending revelation.
  • Playful invention and charm define the register — fanciful conceits, light absurdity, and a narration that delights in its own oddity.

About

What the story runs on.

  • Stories in which a machine intelligence — an AI, computer mind, or sentient program — is a central character or the story's driving problem.
  • Stories centered on robots, androids, cyborgs, or other artificial mechanical beings and their relations with their makers.
  • Stories in which extraterrestrial beings are central — as characters, cultures, or the object of the plot.
  • Stories driven by deliberate modification of genomes — designer organisms, engineered humans, and the consequences of remaking life.
  • Stories about venturing into space to explore — survey missions, astronauts, and the frontier of the unknown beyond Earth.
  • Stories about settling other planets or habitats — founding, sustaining, and governing colonies off Earth.
  • Stories about minds with paranormal abilities — telepathy, telekinesis, precognition, empathy — and how societies handle those who have them.
  • Stories in which staying alive against nature, catastrophe, or scarcity is the central problem.
  • Stories of growing up — a young protagonist crossing from childhood into adult knowledge and responsibility.
  • Stories about who a character truly is — self-discovery, doubled lives, and the search for a self.
  • Stories driven by maneuvering for power — factions, conspiracies, and statecraft conducted in shadow.
  • Stories in which war itself is the subject — combat, occupation, and what warfare does to soldiers and civilians.

    • Fantasy that blends in horror's atmosphere and imagery, keeping a fantastical frame around grim or frightening material.

    • Horror of decaying houses, buried family secrets, and oppressive atmosphere in the Gothic literary tradition.
    • Horror centered on hauntings and the returning dead.
    • Horror located in the mind — paranoia, obsession, and unreliable perception rather than external monsters.
    • Horror built around the reanimated dead and survival amid their outbreaks.
    • Speculative fiction of the strange and uncanny that resists both natural explanation and standard genre categories.
    • Fiction organized around solving a crime or puzzle, typically following an investigator toward the identification of a culprit.
    • A puzzle-first mystery that lays out clues so the culprit's identity can be deduced before the reveal.
    • Crime fiction of moral ambiguity, fatalism, and hard-edged style, set among the corrupt and the doomed.
    • A mystery following the realistic routines of police work — forensics, interviews, and case-building.
    • Fast-paced fiction driven by imminent danger, pursuit, or high-stakes conspiracy, built to sustain tension.
    • A thriller of espionage — agents, tradecraft, and intelligence services in conflict.
    • A thriller centered on lawyers and the courtroom, where litigation carries the suspense.
    • A thriller driven by detailed contemporary or near-future technology, often military or scientific.
    • A thriller whose tension comes from mental states and manipulation between characters rather than external action.
    • Fiction whose central plot is a romantic relationship and its development toward an emotionally satisfying resolution.
    • Romance in which one or both partners are supernatural beings, blending fantasy elements into the love story.
    • Fiction set in a real past period, where the historical setting materially shapes characters and events.

        • Fiction written primarily to amuse, using comedic situations, wit, or parody as its organizing principle.

                No species, the Galactics insist, ever climbs to sapience alone. For a billion years the elder races have "uplifted" their chosen clients — reshaping some promising animal, gene by patient gene, into a thinking being, then binding it through long ages of indenture. Patron lifts client; client one day becomes patron; and every lineage traces back through the vast Galactic Library to the vanished Progenitors who began it all. Then a ragged band of primates arrives at the stars with no patron to claim them — wolflings, self-made, an affront to a hundred thousand years of law — and worse, these humans have already started uplifting neighbors of their own: the neo-dolphins and neo-chimpanzees of Earthclan. David Brin builds this galaxy across two trilogies. The first — Sundiver, the Hugo- and Nebula-winning Startide Rising, and the Hugo-winning The Uplift War — sends an expedition into the Sun, then follows the dolphin-crewed survey ship Streaker as it flees a discovery that sets fanatical star-clans at war, and a chimp-led resistance on an invaded colony world. The second sequence, Uplift Storm — Brightness Reef, Infinity's Shore, Heaven's Reach — descends to Jijo, a forbidden world where six fallen races hide as illegal settlers, and draws every loose thread toward a reckoning. Short fiction fills the margins. This is space opera with an ecologist's conscience: teeming with invented biologies, wry cross-species banter, and real unease about what we owe the minds we make. Begin with Startide Rising — the saga's beating heart, and readable on its own — or take Sundiver first and read straight through in publication order.

The idea came from an object that was at the time believed to exist in the 61 Cygni system, and which might represent an extrasolar planet.

                similar byspace explorationhard science fiction

                From the front flap of the Simon and Schuster first edition: For centuries humanity has dreamed of life and intelligence beyond the Earth; for decades scientists have searched for it in every corner of the sky; for years Project Argus, a vast, sophisticated complex of radio telescopes, has listened for a signal indicating the existence, somewhere in the universe, of extraterrestrial intelligence. Then, one afternoon, the course of human history is changed, abruptly and forever. The Message, awaited for so long, its very possibility doubted by so many, arrives. Contact has been made. Life, intelligence, someone, something beyond Earth, 26 light-years away, in the vicinity of the star Vega, is calling, beaming across space a wholly unexpected message to say that we are not - have never been - alone. In Contact, Carl Sagan, whose Cosmos enthralled millions of readers and television viewers, has brilliantly employed the freedom of fiction to imagine the greatest adventure of all - humanity's first encounter with other intelligent beings. But the novel is not only about contact between humans and extraterrestrials; it is also about contact, down here on Earth, with each other and ourselves. At its center is a brilliant scientist, Eleanor Arroway, director of Project Argos, who is the first to realize that chapter one of human history is over. It is she who is instrumental in decoding the Message - and in persuading world leaders not to treat it as a threat - she who finds her own life changed by the immense challenge of responding to the Message; she who finally journeys out to experience, in circumstances at once profoundly religious and scientific, the most fateful encounter in human history.

The two threads collide across mismatched timescales as the ark ship's crew, cycling in and out of cryosleep, finally reach the spiders' world.
