Obviously, you're not going to use the characters in this book as role models. There's a little bit of everything--eating disorders, sexuality, cursing, violence, drinking, and sex, but in all, it's entertaining. I really enjoyed reading this book and didn't find it as shallow as other teenage books. It was a little creepy, with Alison's disappearance and the messages that are popping up everywhere, but it added an edge to the story. The characters are all a little extreme, in my opinion, but that makes the story interesting. I say read it if you're looking to relax but to also get a little something from it. It's a little mature, but I wouldn't say 15 and up. We all know about this stuff anyway.
