Seventeen-year-old Lorelei “Lori” Blakely knows better than to wander the uninhabited Dead Zone—Dad would kill her if she did. But that doesn’t stop her from wandering into the city ruins just a train ride away. That night, she’s able to perform stunts she’d never be able to do—like jumping from her window in her apartment to the parking garage next door. Not only that, but she wanders into a part of the city she’d never go to. There, she runs into Gavin, the guy who knows the truth behind the Demon Research Center’s tactics, and who says she now has a demon’s soul inside her. Lori doesn’t know what to think—about the demon in her soul, about how Gavin’s opinion on her seems to bounce between good and bad. And then there’s the Demon Research Center, the place Dad wants to take her, where they’re supposed to “fix” her. But she knows one thing: no matter what, she won’t let the demon inside ruin her life.
