Lockstep by Karl Schroeder
Toby McGonigal is lost in space when his ship has a malfunction. When he awakes he finds that it is 14,000 years later and the world has both changed unrecognizably but remained similar due to a scheme where societies sleep for 30 years and awake for 1 month. Not only are members of his family still alive, they are part of a conspiracy where Toby is revered as a God. Toby must find people he can trust and determine a way to survive.
From the cover I thought this was going to be one of those throw off novels that are great for plane rides and trips. However, the book was pretty developed and the premise of the Lockstep universe well thought out. The book should appeal to science fiction fans as well as new adult readers.
