Allie enters sixth-grade at an elite magnet school with her best friend Tam, but as these things have a way of doing, she and Tam start to drift apart. And as the year progresses, Allie struggles with her identity, as she starts playing offense in soccer (after being on defense all the time), becoming friendly with geeky Orren, and learning to do things because SHE enjoys them, rather than to be cool. Still, she struggles with what she really wants.
This is pretty much a by-the-numbers book about changing friendships. It's got a terribly clever thing going with made-up words like "glommers", "norks" and so on. You'll be able to predict where the story is going, but that doesn't diminish it's fun. So, a good book, but nothing outrageously original.
