Camp Confidential by Melissa J. Morgan
Summer camp means lots of things: new friends, roommates, bug bites, bathroom duty...But it's also a chance to be on your own and to reinvent yourself. A shy girl can become the belle of the ball, and a jock might find new competition. Natalie, Jenna, Grace, and Alex have all found themselves at Camp Lakeview for different reasons. And each is keeping a secret. But if everyone is hiding something, how will they ever become friends?
