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.

Spaceships do. A flurry of top-level government meetings produces the inescapable conclusion: Whatever built that ship is at least one hundred years ahead in hard and soft technology, and whoever can get their hands on it exclusively and bring it back will have an advantage so large, no other nation can compete.

                  The only novel of its year to be nominated for both the Hugo and Nebula Awards. Starplex won Canada's Aurora Award for best novel of the year. For nearly twenty years Earth's space exploration had exploded outward, thanks to a series of mysterious, artificial wormholes. No one knows who created these interstellar passages, yet they have brought the far reaches of space immediately close. For Starplex Director Keith Lansing, too close. Discovery is superseding understanding. And when an unknown vessel — with no windows, no seams, and no visible means of propulsion — arrives through a new wormhole, an already battle-scarred Starplex could be the starting point of a new interstellar war . . . ROBERT J. SAWYER has won the Hugo, Nebula, John W. Campbell Memorial, Seiun, and Aurora Awards, all for best science fiction novel of the year. His novels include Hominids, Rollback, Wake, and FlashForward (basis for the TV series).

                  Marshall Hunter only wanted to fly: the faster, the higher, the better. But a life of rescuing wayward spacefarers and derelict satellites in the cislunar cruiser U.S.S. Borman is far from the adventure he'd imagined. But his fortunes change when a billionaire couple goes missing on their way to a near-Earth asteroid. Out of contact and on a course that will eventually send them crashing into Mars, the nuclear-powered Borman is dispatched on an audacious, high-speed interplanetary run to bring the couple home. As they approach the asteroid, however, the Borman itself becomes hopelessly disabled. With the Borman suddenly out of commission and far beyond reach, cislunar space begins falling into chaos as critical satellites fail and valuable lunar mineral shipments begin disappearing in transit. Nothing is as it seems, and Marshall Hunter and the rest of the crew suspect none of it is by coincidence.
