"The mother of one of the two shooters at Columbine High School draws on personal recollections, journal entries and video recordings to piece together what led to her son's unpredicted breakdown and share insights into how other families might recognize warning signs,"--NoveList. On April 20, 1999, Eric Harris and Dylan Klebold walked into Columbine High School in Littleton, Colorado. In a matter of minutes, they killed twelve students and a teacher and wounded twenty-four others before taking their own lives. For the last sixteen years, Sue Klebold, Dylan's mother, has lived with the indescribable grief and shame of that day. How could her child, the promising young man she had loved and raised, be responsible for such horror? And how, as his mother, had she not known something was wrong? Here she chronicles her journey as a mother trying to come to terms with the incomprehensible, shedding light on one of the most pressing issues of our time.--Adapted from book jacket.
