"A Tom Doherty Associates Book."

"When seventeen-year-old Toby McGonigal is lost in space and separated from his family, he expects his next drift into cold sleep to be his last. After all, the planet he's orbiting is frozen and sunless, and its cities are dead. But when Toby wakes again, he's surprised to discover a thriving world wandering a strange and prosperous galaxy, and something stranger still - that he's been asleep for fourteen thousand years. Welcome to the Lockstep empire, a sublight civilization maintained by careful hibernation. Here citizens survive for millenia, traveling in slumber for decades on the long voyages between worlds, awakened for mere weeks at a time. Not only are the lockstep worlds the new center of the galaxy, but Toby is shocked to learn that the empire is still ruled by its founding family: his own. Toby's brother, Peter, has become a terrible tyrant. Suspicious of his long-lost brother's reappearance, and careful to guard the McGonigal DNA that controls the lockstep hibernation cycles, Peter sees Toby as a threat to his regime. Now, with the help of a lockstep girl named Corva, Toby must survive the forces of this new empire, outwit his siblings, and save human civilization"--Back cover.
