Zones of thought series

"Ten years have passed on Tines World, where Ravna Bergnsdot and a number of human children ended up after a disaster that nearly obliterated humankind throughout the galaxy. Ravna and the pack animals for which the planet is named have survived a war, and Ravna has saved more than one hundred children who were in cold-sleep aboard the vessel that brought them. While there is peace among the Tines, there are those among them--and among the humans--who seek power...and no matter the cost, these malcontents are determined to overturn the fledgling civilization that has taken root since the humans landed. On a world of fascinating wonders and terrifying dangers, Vernor Vinge has created a powerful novel of adventure and discovery that will entrance the many readers of A Fire Upon the Deep. Filled with the inventiveness, excitement, and human drama that have become hallmarks of his work, this new novel is sure to become another great milestone in Vinge's already stellar career. "--

Thousands of years in the future, humanity is no longer alone in 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 this galactic threat, Ravna crash lands on a strange world with a ship-hold full of cryogenically frozen children, the only survivors from a destroyed space-lab. They are taken captive by the Tines, an alien race with a harsh medieval culture, and used as pawns in a ruthless power struggle.
