The book was written in a rather awkward way. I feel like this book only breached the surface on certain cases, and I was confused as to why Eric Harris and Dylan Klebold were not included in this book- since Kip Kinkel was, and he was a school shooter whose fame due to his shooting pales in comparison to the incident at Columbine. The author also seems to point fingers at the fact that all these children came from troubled backgrounds (violent families, dysfunctional families, etc)- though many do- but at the same time, there are often other reasons that lead people to kill. I felt there was no true depth to this book. It was a decent read to pass the time, but as someone who enjoys true crime, this was a disappointment.
