This book conveys messages that all adolescents, teachers, and other school faculty need to hear and understand. It shows how damaging bullying can be, why it needs to be prevented, and that violence and revenge are NOT the answers to the problem. The two shooters were portrayed as good children, but bullying caused one of them to spiral into a deep depression and the other to develop anger problems and violent tendencies. While the story is told from many different people who have very different opinions about what happened, they all agree on one thing: the shooting only made things worse for everyone. Even the friends of the shooters, who wanted revenge on the bullies, felt that the shooting was horrible and made things much worse off for them. The book, overall, conveys a positive message. There is some mild violence, which is not at all graphic, and some characters consume alcohol, but it is nothing that children haven't already heard about before. I read this book when I was 12, along with the rest of my seventh grade class, and I didn't see anything wrong with it. I would especially recommend this book to all teachers, so they could understand how to prevent bullying and future school shootings.
