I still remember the day Dylan Klebold and Eric Harris walked into Columbine High School in Colorado, killed twelve students, a teacher and wounded twenty-four others before committing suicide. It wasn’t the first such shooting, but it was the biggest at the time, ushering in a new era of fear for school aged children. Many of us wondered how such a tragedy could occur. Where were Dylan and Eric’s parents? In this book, Dylan’s mother, Sue, shares her grief and shame, and with unflinching honesty, describes the signs she might have missed. What’s truly alarming about her story, though, is that the Klebolds were a normal middle class family. There may have been subtle signs Dylan was in trouble, but no large red flags. The Klebolds could be any of us. And, until we remove all impediments to treating people for mental health, the scenario is bound to happen again and again. A frightening, yet fascinating, glimpse inside the life of a mass murderer in the making.
