The author of the 400,000-copy best seller On Killing reveals how violent video games have ushered in a new era of mass homicide - and what we must do about it.

Paducah, Kentucky, 1997: a 14-year-old boy shoots eight students in a prayer circle at his school. Littleton, Colorado, 1999: two high school seniors kill a teacher, 12 other students, and then themselves. Utoya, Norway, 2011: a political extremist shoots and kills 69 participants in a youth summer camp. Newtown, Connecticut, 2012: a troubled 20-year-old man kills 20 children and six adults at the elementary school he once attended.

What links these and other horrific acts of mass murder? A young person's obsession with video games that teach to kill.

Lt. Col. Dave Grossman, who in his perennial best seller On Killing revealed that most of us are not "natural born killers" - and who has spent decades training soldiers, police, and others who keep us secure to overcome the intrinsic human resistance to harming others and to use firearms responsibly when necessary - turns a laser focus on the threat posed to our society by violent video games.

Drawing on crime statistics, cutting-edge social research, and scientific studies of the teenage brain, Col. Grossman shows how video games that depict antisocial, misanthropic, casually savage behavior can warp the mind - with potentially deadly results. His audiobook will become the focus of a new national conversation about video games and the epidemic of mass murders that they have unleashed.
