4After 200 years in cryosleep, Jaybee Corbell awakens to find that his mind has been downloaded to another body and he's in servitude to a harsh future State. After his escape via a spaceship, he traverses such vast distances--with accompanying time dilations--that he returns to Earth 3 million years later to discover a world wholly alien to the one he'd left. A.E. van Vogt wrote, "This fantastic novel is a mix of Niven hard science and a time-travel concept to boggle the mind." "Larry Niven is one of the giants of modern science fiction." - Mike Resnick "His tales have grit, authenticity, colorful characters and pulse-pounding narrative drive. Niven is a true master " - Frederik Pohl "Niven's intoxicating concepts, ideas, scientific extrapolations, and exotic hardware buffle up from every page. Rich in imagination and astonishing in breath ... will challenge the most sophisticated readers." - ALA Booklist "This fantastic novel is a mix of Niven hard science and a time-travel concept to boggle the mind...even after the last line the feeling remains of the story still rushing on into the magic distance of the universe." - A.E. van Vogt "Terrific fun " - Kirkus Reviews
