Be prepared- this book will probably spark a lot of debate, which will likely place this book on hundreds of school reading lists. It'll be on this list for a good reason. While there are books out there that deal with the subjects of online bullying, school bullying, and peer pressure, I haven't really read many that approach it in the way that this has. This review will have some slight spoilers because in order to describe why I loved this so much I'll have to spoil one or two small things. Don't worry- none of the large plot points will be revealed. 
 What made this fairly unique for me is that this book wasn't narrated from the viewpoint of our lovely,doomed-to-be-bullied character of Carolyn. No, it's actually told from the viewpoint of an anonymous female narrator that's probably just as much to blame for Carolyn's woes as the bullies are and what makes it so horrifying is that you can see where things are going to go fairly early on in the book. People's reactions to the bullies and to what Carolyn is pretty much what is called the "boiling frog principle". If you put a frog in a boiling pot of water, the frog will hop out quickly. If you turn that heat up slowly, the frog will remain in the pot and be boiled to death. 
 That's pretty much what happens here. Carolyn's fall from grace and her descent into awful bullying happens so relatively slowly that people just see it as a matter of course. When her bullying does intense people just sort of shrug and don't do anything because that's it's just what happens. People think it's awful and there are concerns about stepping in and becoming a new target, but this book really explores the mentality of the people viewing the bullying- both students and adults. The latter is probably what made this a little hard to read at points because with books like this we expect the teens to be awful with one another, but we do expect the teachers to step in to some degree and Bannan does go out of her way to show how this can happen- how teachers can watch a teen girl go from a fairly lively person to a shell of her former self. Carolyn is a fragile character to begin with, something that many of the teachers (one of whom tries to put herself out as the "cool teacher that notices things") plain overlook. 
 I can't recommend this book enough. It doesn't really matter what your age or gender is- this has a wide appeal. There are some aspects to this that are sort of what you'd expect from this type of read, but Brennan tries really hard to put a fresh perspective on things and she succeeds.
