This is a really great book that covers just about every aspect you can think of with the Columbine shooting. I’ve had this book for a minute but just read it because I saw something like one of the survivors recently ODed (I think). Anyway it’s crazy how much information the two dudes (Eric and Dylan) left behind. Cullen does a lot of diary analysis and stuff. The fact that Eric even had a diary leaves so much room for understanding who he thought he was.
