Columbine (2009) by Dave Cullen (link)

A gruesome tale of something that should have never happened. While I do think that this book is longer than it needed to be—there’s a great deal of repetition that I believe is unnecessary—I thoroughly enjoyed it, if anyone can say such a thing about the documentation of a tragedy. If anything, this is an interesting perspective into the psyche of a pair of killers and how a community has had to work through their grief, sadness, and anger. It’s not the right book for most people, and I would never read it again, but it is worth the time for the right type of person.
