A gripping narrative that spans five decades, The Looming Tower 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. Lawrence Wright re-creates firsthand the transformation of Osama bin Laden and Ayman al-Zawahiri from incompetent and idealistic soldiers in Afghanistan to leaders of the most successful terrorist group in history. He 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.
