I don't know how I feel about this book.

To say I enjoyed it would be weird, but the narration was lively and engaging and I found the subject well presented and interesting.

I don't know much about Columbine so I went into this without any preconceived ideas about the school shooting.

This book is mostly mulling over the why. And seems to come to the conclusion that Eric Harris was a psychopath and Dylan Klebold was depressed.

I'm not sure I found the argument entirely convincing all the time, but have no real evidence or solid ground on which to base that view and neither do I have any more compelling arguments to offer.
