The Looming Tower, Lawrence Wright's gripping narrative spanning five decades, explains in unprecedented detail the growth of Islamic fundamentalism, the rise of Al-Qaeda, and the intelligence failures that culminated in the attacks on the World Trade Center. The Pulitzer Prize-winning author follows FBI counterterrorism chief John O'Neill as he uncovers the emerging danger from Al-Qaeda in the 1990s and struggles to track this new threat. Just published in paperback, The Looming Tower was a National Book Award Finalist, a Time, Newsweek, Washington Post, Chicago Tribune, and New York Times Book Review Best Book of the Year. Lawrence Wright joins Larry Mantle to talk about the history of Al-Qaeda and the events and personalities that led to the 9/11 disaster.
