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.
  • The book works as comfort reading — low tension, a soothing pace, and an atmosphere the reader can unwind in.
  • 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 extraterrestrial beings are central — as characters, cultures, or the object of the plot.
  • Stories about venturing into space to explore — survey missions, astronauts, and the frontier of the unknown beyond Earth.
  • Stories structured as a quest — a journey undertaken to find, deliver, or destroy something of great import.
  • Stories in which staying alive against nature, catastrophe, or scarcity is the central problem.
  • Stories of lovers kept apart by law, family, faith, or station, where the obstacle to love is the plot.
  • Stories in which a friendship — its making, testing, or loss — is the emotional center.
  • 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 about rising against rulers — uprisings, resistance movements, and revolutions and their aftermaths.
  • Stories in which war itself is the subject — combat, occupation, and what warfare does to soldiers and civilians.
  • Stories organized around investigating a killing — the case, the clues, and the pursuit of the killer, in any genre's clothing.

                  From the front flap of the Tor first printing: "Humanity has spread to every star within 500 light-years of its half-forgotten origin, coloring the sky with a haze of habitats. Societies rise and fall. Incautious experiments burn fast and fade. On the fringes, less modified humans get on with the job of settling a universe that has, so far, been empty of intelligent life. The ancient starship But the Sky, My Lady! The Sky! is entering orbit around a promising new system after a four hundred year journey. For its long-lived inhabitants, the centuries have been busy. Now a younger generation is eager to settle the system. The ship is a seed-pod ready to burst. Then they detect curious electromagnetic emissions from the system's Earth-like world. As the nature of the signals becomes clear, the choices facing the humans become stark. On Ground, second world from the sun, a young astronomer searches for his system's outermost planet. A moving point of light thrills, then disappoints him. It's only a comet. His physicist colleague Orro takes time off from trying to invent a flying-machine to calculate the comet's trajectory. Something is very odd about that comet's path. They are not the only ones for whom the world has changed. "We are not living in the universe we thought we lived in yesterday. We have to start learning the world all over again.""

                  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.

She refused to get on the cryo ships, refused to leave the only world she could call home. And when they finally came for her, she hid, not that the authorities looked all that hard for one crazy old woman. Now Ofelia is alone, content to live with no more demands on her self or her time, the only remaining settler on an abandoned planet. The new settlers arrive. At first she fears that they have come to reoccupy the settlement she has come to think of as hers - but they land far away. And as Ofelia secretly listens, they are slaughtered to the last child by stone-age aliens no one knew were there. Now it will be up to Ofelia to save the aliens from Earth's wrath...

When a new homeworld is discovered and preparations are made to abandon the fleet, the now sentient computer realizes it cannot assist them if they leave.

Following the signals, the computer turns its fleet of spider-shaped ships toward the planet Earth. " ― quoted from this book's Amazon product page as of 2022-06-09.

                  "Centuries after the ecological collapse of Earth, humanity has spread among the stars. Under the governance of the League, our endless need for resources has driven us to colonize hundreds of planets, all of them devoid of other sentient life. Humanity is apparently alone in the universe. Then comes the sudden, brutal decimation of Kassa, a small farming planet, by a mysterious attacker. The few survivors send out a desperate plea for aid, which is answered by two unlikely rescuers. Prudence Falling is the young captain of a tramp freighter. She and her ragtag crew have been on the run and living job to job for years, eking out a living by making cargo runs that aren't always entirely legal. Lt. Kyle Daspar is a police officer from the wealthy planet of Altair Prime, working undercover as a double agent against the League. He's been undercover so long he can't be trusted by anyone--even himself. While flying rescue missions to extract survivors from the surface of devastated Kassa, they discover what could be the most important artifact in the history of man: an alien spaceship, crashed and abandoned during the attack. But something tells them there is more to the story. Together, they discover the cruel truth about the destruction of Kassa, and that an imminent alien invasion is the least of humanity's concerns.

                  Cities in Flight is a four-volume series of science fiction novels and short stories by American writer James Blish, originally published between 1950 and 1962, which were first known collectively as the "Okie" novels. The series features entire cities that are able to fly through space using an anti-gravity device, the spindizzy. The stories cover roughly two thousand years, from the very near future to the end of the universe. One story, "Earthman, Come Home", won a Retro Hugo Award in 2004 for Best Novelette. Since 1970, the primary edition has been the omnibus volume first published in paperback by Avon Books. Over the years James Blish made many changes to these stories in response to points raised in letters from readers.
