What kind of person is at your core?Molly O'Keefe's boyfriend, Trevor, is moving too fast, but when she catches him kissing his ex, Molly thinks it might be her own fault. After all, it was her idea to take things slow. In fact, her best friend, Vanessa, recently talked her into buying a neon spandex Halloween costume, and her nine-year-old neighbor, Claire, somehow got her to participate in a sixteen-mile walkathon. Despite Trevor’s apologies and Vanessa’s attempts to hook her up with rebound guys, Molly is utterly heartbroken. Then she finds comfort in a most unusual place: Girl Corps, a club Claire belongs to. As a fifteen-yearold, Molly hardly fits the Girl Corps profile. Still, she can’t deny that being with the little girls in the group gives her a sense of confidence and identity. But now Molly’s newly enlightened self is at odds with almost everyone in her life. As for Trevor, he won’t leave Molly alone, and that means trouble, because whether she likes it or not, Molly still has feelings for him. Will Molly turn her back on what she has learned, or will she stand her ground and embrace the strong girl at her core?
