"On April 20, 1999, two boys left an indelible stamp on the American psyche. Their goal was simple: to blow up their school and to leave 'a lasting impression on the world.' Their bombs failed, but the ensuing shooting defined a new era of school violence ... Dave Cullen delivers 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 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. Drawing on hundreds of interviews, thousands of pages of police files, FBI psychologists, and the boys' tapes and diaries, he gives a complete account of the Columbine tragedy ... A close-up portrait of violence, a community rendered helpless, and police blunders and cover-ups, it is a human portrait of two killers"--From publisher description.
