内容简介：
"My name is Selma Pavelchuk. But you can just call me the Invisible Girl. Especially when I'm standing next to Jodie-the prettiest girl in our class, the girl all the guys want to hook up with, the only girl who wears a bikini on swim days at the Y and my best friend. It's not easy being the popular girl's best friend. But for Selma, it's better than being the geeky nobody she was before she and Jodie started hanging out. Most of the time. But when the girls spend a week together at Jodie's cottage, Selma starts to seriously think about making some new friends. Jodie's self-centeredness and mean streak are getting old. And then there are the guys: John, the male-model wannabe, and Jodie's brainy brother Mark. Selma's crushing on both of them, but there's no way anything's going to happen with either one-at least not on Jodie's watch. It's quickly becoming clear to Selma what she has to do but breaking up with Jodie just may be the hardest thing she's ever done.
