In remembrance of the 25th anniversary, this definitive account of Columbine examines the aftermath and significance of the massacre: "a staggering work of journalism" (Washington Post). So begins a new preface, illustrating how Columbine became the template for nearly two decades of "spectacle murders." It is a false script, seized upon by a generation of new killers. In the wake of Newtown, Aurora, and Virginia Tech, the imperative to understand the crime that sparked this plague grows more urgent every year. Dave Cullen was one of the first reporters on the scene, and he spent ten years on this book, the definitive account. With a keen investigative eye and psychological acumen, he draws on mountains of evidence, insight from the world's leading forensic psychologists, and the killers' own words and drawings-several reproduced in a new appendix. Cullen paints raw portraits of two polar opposite killers. They contrast starkly with the flashes of resilience and redemption among the survivors. "Excellent...amazing how much still comes as a surprise."-New York Times Book Review "Like Capote'sIn Cold Blood, this tour de force gets below the who and the what of a horrifying incident to lay bare the devastating why."-People "A staggering work of journalism."Washington Post
