Jaybee Corbell awoke after more than 200 years as a corpsicle -- in someone else's body, and under sentence of instant annihilation if he made a wrong move while they were training him for a one-way mission to the stars. But Corbell picked his time and made his own move. Once he was outbound, where the Society that ruled Earth could not reach him, he headed his starship toward the galactic core, where the unimaginable energies of the Universe wrenched the fabric of time and space and promised final escape from his captors. Then he returned to an Earth eons older than the one he'd left...a planet that had had 3,000,000 years to develop perils he had never dreamed of -- perils that became nightmares that he had to escape...somehow!

When a diphtheria epidemic hits her 1840 village, thirteen-year-old Jessie discovers it is actually a 1996 tourist site under unseen observation by heartless scientists, and it's up to Jessie to escape the village and save the lives of the dying children.

Wan-To was the oldest and must powerful intelligence in the universe, a being who played with star systems as a child plays with marbles. Matter occupied so tiny a part of his vast awareness that humans were utterly beneath his notice. The colonists of Newmanhome first suffered the effects of Wan-To's games when their planet's stars began to shift, the climate began to cool down, and the colony was forced into a desperate struggle to survive. Viktor Sorricaine was determined to discover what force had suddenly sent his world hurtling toward the ends of the universe. And the answer was something beyond the scope of his imagination -- even if he lived for 4000 years...

Winner of the Hugo and Nebula Awards for best novel Four travelers come to the ringworld. . . Louis Wu: human and old; bored with having lived too fully for far too many years. Seeking a challenge, and all too capable of handling it. Nessus: a trembling coward, a puppeteer with a built-in survival pattern of nonviolence. Except that this particular puppeteer is insane. Teela Brown: human; a wide-eyed youngster with no allegiances, no experience, no abilities. And all the luck in the world. Speaker-To-Animals: kzin; large, orange-furred, and carnivorous. And one of the most savage life-forms known in the galaxy. Why did these disparate individuals come together? How could they possibly function together? And where, in the name of anything sane, were they headed?
