Prize-winning journalist Steve Coll has spent years reporting from the Middle East, accessed previously classified government files and interviewed senior US officials and foreign spymasters. Here he gives the full inside story of the CIA's covert funding of an Islamic jihad against Soviet forces in Afghanistan, explores how this sowed the seeds of bn Laden's rise, traces how he built his global network and brings to life the dramatic battles within the US government over national security. Above all, he lays bare American intelligence's continual failure to grasp the rising threat of terrrorism in the years leading to 9/11 - and its devastating consequences.
