Living in a DC trailer park, Nearly Boswell knows better than to share anything that would make her a target with her classmates. But when a serial killer goes on a killing spree and starts attacking students, leaving cryptic ads in the newspaper that only Nearly can decipher, she confides in the one person she shouldn't trust: the new guy at school—a reformed bad boy working undercover for the police, doing surveillance. . . on her. Nearly might be the one person who can put all the clues together, and if she doesn't figure it all out soon—she'll be next.
