Peter L. Bergen, author of the bestselling book Holy War, Inc., offers an astounding, unparalleled portrait of Osama bin Laden, comprised of Bergen's own interviews with more than fifty people who have known bin Laden personally, from his brother-in-law to his high school English teacher to former members of al Qaeda. The resulting collage of voices and memories affords an unprecedented glimpse into the life and true nature of the man directly responsible for the largest terror attack in history. How was bin Laden transformed from a shy, polite schoolboy to commander of the world's most formidable terrorist organization? Where was he on 9/11? How did he escape from Tora Bora? Is al Qaeda a top-down organization or a loose ideological alliance? What is it about this man that draws hundreds of thousands of followers and makes men willing to fly airplanes into buildings at his command? This definitive and engaging portrait gives the American public its first true, enduring insight into a man who has declared us his greatest enemy.
