In a riveting piece of journalism nearly ten years in the making, comes the story of Columbine that none of us knew. In this revelatory book, Dave Cullen has delivered a profile of teenage killers that goes to the heart of psychopathology. He lays bare the callous brutality of mastermind Eric Harris and the quavering, suicidal Dylan Klebold, who went to the prom three days earlier and obsessed about love in his journal. The result is an astonishing account of two good students with lots of friends, who were secretly stockpiling a basement cache of weapons, recording their raging hatred, and manipulating every adult who got in their way. They left signs everywhere, described by Cullen with a keen investigative eye and psychological acumen. Drawing on hundreds of interviews, thousands of pages of police files, FBI psychologists, and the boys' tapes and diaries, he gives the first complete account of the Columbine tragedy.
