Lockstep

Seventeen-year-old Toby McGonigal finds himself adrift in space, only to awaken 14,000 years later on a thriving planet within the Lockstep Empire, where civilization depends on hibernation cycles. As he navigates this strange galaxy, Toby discovers that his brother Peter has become a tyrannical ruler, viewing his return as a threat to his reign. Teaming up with a local girl named Corva, Toby must outsmart his siblings and uncover a way to protect humanity's future amid the empire's complex politics. Karl Schroeder's Lockstep offers an inventive take on hard science fiction and space opera.
