Summer Camp: MJ's Camp Crisis

In this e-book, MJ wasn't sold on going to camp to begin with, but after her best friend bales on her, she's even less excited about spending her summer with a mass of overly perky girls. Fortunately she makes fast friends with her bunkmate Zoe who seems familiar right from the start. Then MJ realizes why; Zoe is the daughter of the lead singer of MJ's favorite band. Should MJ tell Zoe she knows who she is or keep things quiet?
