Across the Universe — Beth Revis

AMY IS A CRYOGENICALLY FROZEN PASSENGER aboard the spaceship Godspeed. She has left her boyfriend, friends -- and planet -- behind to join her parents as a member of Project Ark Ship. Amy and her parents believe they will wake on a new planet, Centauri-Earth. three hundred years in the future. But fifty years before Godspeed's scheduled landing, cryo chamber 42 is mysteriously unplugged, and Amy is violently woken from her frozen slumber.

Someone tried to murder her.

Now, Amy is caught inside a tiny world where nothing makes sense. Godspeed's 2,312 passengers have forfeited all control to Eldest, a tyrannical and frightening leader. And Elder, Eldest's rebellious teenage heir, is both fascinated with Amy and eager to discover whether he has what it takes to lead.

Amy desperately wants to trust Elder. But should she put her faith in a boy who has never seen life outside the ship's cold metal walls? All Amy knows is that she and Elder must race to unlock Godspeed's hidden secrets before whoever woke her tries to kill again.
