On April 20, 1999, Eric Harris and Dylan Klebold left an indelible stamp on the American psyche. Their plan was staggering: to blow up their school, surpass Oklahoma City in horror, and leave "a lasting impression on the world." The bombs failed. But the unprecedented attack unleashed a new era of violence in schools—branding every future shooting "another Columbine."

When we think of Columbine, we think of the Trench Coat Mafia; Cassie Bernall, mistaken Columbine martyr; and Patrick Ireland, "the boy in the window"—the whole world watching his gutsy escape. Now, in a gripping work of journalism a full decade in the making, comes the story we never knew. In this revelatory book, Dave Cullen debunks the myths and produces a profile of teen killers that burrows to the core of psychopathology. He reveals two radically different killers: Eric Harris, the callously brutal mastermind, and Dylan Klebold, the quivering depressive who journaled obsessively about love and attended the Columbine prom three days before opening fire.

Columbine unfolds seamlessly, in an unforgettable tale of two honor students with a healthy circle of friends, secretly stockpiling a cache of weapons in the basement. They recorded their vitriol on film while manipulating every adult who could have stopped them. Eric Harris and Dylan Klebold left warnings all around them—described by Cullen with a sharp investigative eye and psychological acumen. Culling from hundreds of interviews, thousands of police files, testimony from world-class psychologists brought in by the FBI, and the boys' videos and journals, he delivers the first comprehensive account of the tragic Columbine school shooting.

A riveting tale of murder, redemption, police cover-up, and a town torn apart—the haunting cautionary tale for our age. COLUMBINE-Dave Cullen
