Charlie is fifteen. She's just moved to a new school and nothing is going right. She's hanging around with a girl she can't stand, her mother is a grief-stricken, wine-sodden mess, and she has no one to talk to except the pages of her diary. Everything seems hopeless. And then she meets Kate. Kate is sixteen, she's a singer, and she's wonderful. She's everything Charlie isn't, and she makes Charlie's life seem bearable. But when Kate announces she's leaving, Charlie is desperate. Desperate enough to do anything - anything - to get Kate to stay.
