Book Description:
Addie Downs and Valerie Adler will be best friends forever. That's what Addie believes after Valerie moves across the street when they're both nine years old. But in the wake of betrayal during their teenage years, Val is swept into the popular crowd, while mousy, sullen Addie becomes her school's scapegoat.

Flash-forward 15 years. Valerie Adler has found a measure of fame and fortune working as the weathergirl at the local TV station. Addie Downs lives alone in her parents' house in their small hometown of Pleasant Ridge, Illinois, caring for a troubled brother and trying to meet Prince Charming on the Internet. She's just returned from Bad Date #6 when she opens her door to find her long-gone best friend standing there, a terrified look on her face and blood on the sleeve of her coat.

"Something horrible has happened," Val tells Addie, "and you're the only one who can help."
