Unsouled — Neal Shusterman

Connor and Lev are on the run after the destruction of the Graveyard, the last safe haven for AWOL Unwinds. But for the first time, they're not just running away from something. This time, they're running toward answers, in the form of a woman Proactive Citizenry has tried to erase from history itself. If they can find her, and learn why the shadowy figures behind unwinding are so afraid of her, they may discover the key to bringing down unwinding forever.

Cam, the rewound boy, is plotting to take down the organization that created him. Because he knows that if he can bring Proactive Citizenry to its knees, it will show Risa how he truly feels about her. And without Risa, Cam is having trouble remembering what it feels like to be human.

With the Juvenile Authority and vindictive parts pirates hunting them, the paths of Connor, Lev, Cam, and Risa will converge explosively -- and everyone will be changed.
