Great information about teens who kill, be it their families, their schoolmates, or strangers. The book starts out with one of the first teen killers, Harry Hebard, and then examines several other cases as well. There are interesting breakdowns of the different categories of killers as well. It is obvious that there was quite a lot of research done for this book. It is a short read, but it packs a lot of information. For true crime fans, this is a must read.
