On July 20, 2012, 12 people were killed and 70 wounded at a mass shooting in a movie theater in Colorado. In 1999, 12 kids and one teacher at Columbine High School were murdered by two students. In 2012, 20 children and seven adults were killed at Sandy Hook Elementary. Thirty-two were killed at Virginia Tech. Twelve killed at the Washington Navy Yard. In May 2014, after posting a YouTube video of "retribution" and lamenting a life of "loneliness, rejection, and unfulfilled desires," a lone gunman killed six and wounded seven in Isla Vista. All of these acts of violence were committed by young men between the ages of 18 and 30.

Mass violence committed by young people is now an epidemic. In the first 14 school days of 2014, there were seven school shootings, compared to 28 school shootings in all of 2013. The reasons behind this escalating violence and the cultural forces that have impugned a generation is the subject of this important new book.

New York Times best-selling author Stephen Singular has often examined violence in America in his critically acclaimed books. Here he has teamed with his wife, Joyce, for their most important work yet - one that investigates why America keeps producing twentysomething mass killers. Their reporting has produced the most comprehensive look at the Aurora shooting yet and draws upon the one group left out of the discussion of violence in America: the twentysomethings themselves.

While following the legal proceedings in the Aurora shooting, The Spiral Notebook is full of interviews with Generation Z, a group dogged by big pharma and antidepressants and ADHD drugs, by a doomsday/apocalyptic mentality present since birth, and by an entertainment industry that has turned violence into parlor games.

Provocative and eye opening, The Spiral Notebook is a glimpse into the forces that are shaping the future of American youth, an entire generation bathed in the violence committed by their peers.
