Callie Miller's mother is her polar opposite: charismatic, outgoing, and social. And sometimes, she hates her for it. For instance, when Mrs. Miller invites her good friend, Colleen Gibson, and her family to their beach house for the summer, Callie is furious. That means that she'll have to spend three whole weeks with Luke--Mrs. Gibson's athletic, smart, and popular son, who goes to her school. Callie has never had over five minutes of contact with him, and now, three weeks? A lot could happen in so little time.
