When her best friend, Meg, drinks a bottle of industrial-strength cleaner alone in a motel room, Cody is understandably shocked and devastated. She and Meg shared everything—so how was there no warning? But when Cody travels to Meg’s college town to pack up the belongings left behind, she discovers that there’s a lot that Meg never told her. About her old roommates. About Ben McAllister, the boy with a guitar and a sneer, and some secrets of his own. And about an encrypted computer file that Cody can’t open—until she does, and suddenly everything Cody thought she knew about her best friend’s death gets thrown into question.
