Katy knows the world changed the night the Luxen came. She can't believe Daemon welcomed his race or stood by as his kind threatened to obliterate every last human and hybrid on Earth. But the lines between good and bad have blurred, and love has become an emotion that could destroy her—could destroy them all.

Daemon will do anything to save those he loves, even if it means betrayal. They must team with an unlikely enemy if there is any chance of surviving the invasion. But when it quickly becomes impossible to tell friend from foe, and the world is crumbling around them, they may lose everything— even what they cherish most—to ensure the survival of their friends...and mankind.

War has come to Earth. And no matter the outcome, the future will never be the same for those left standing.

This edition includes SHADOWS, a Lux Prequel Novella

A Fire Upon the Deep is the big, breakout book that fulfills the promise of Vinge's career to date: a gripping tale of galactic war told on a cosmic scale. Thousands of years hence, many races inhabit a universe where a mind's potential is determined by its location in space, from superintelligent entities in the Transcend, to the limited minds of the Unthinking Depths, where only simple creatures and technology can function. Nobody knows what strange force partitioned space into these "regions of thought," but when the warring Straumli realm use an ancient Transcendent artifact as a weapon, they unwittingly unleash an awesome power that destroys thousands of worlds and enslaves all natural and artificial intelligence.

Fleeing the threat, a family of scientists, including two children, are taken captive by the Tines, an alien race with a harsh medieval culture, and used as pawns in a ruthless power struggle. A rescue mission, not entirely composed of humans, must rescue the children-and a secret that may save the rest of interstellar civilization.
