I WAS HERE - Penguin USA

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 Meg never told her. About her old roommates, the sort of people Cody never would have met in her dead-end town in Washington. About Ben McCallister, 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.
