The Black Banners: The Inside Story of 9/11 and the War Against al-Qaeda by Ali H. Soufan

5.0

Recommended because it's the most thorough history of the FBI's pursuit of Al-Qaeda both before and after 9/11. The author is a former FBI interrogator, who gained valuable intelligence from detainees by "getting into their heads" based on carefully researched personal histories. Also a sobering story of the turf wars between the FBI and CIA, and that if communication between the two had been better perhaps 9/11 could have been prevented.
