The faithful spy : a novel / Alex Berenson

John Wells is the only American CIA agent ever to penetrate al Qaeda. Since before the attacks in 2001, Wells has been hiding in the mountains of Pakistan, biding his time, building his cover." "Now, on the orders of Omar Khadri - the malicious mastermind plotting more al Qaeda strikes on America - Wells is coming home. Neither Khadri nor Jennifer Exley, Wells's superior at Langley, knows quite what to expect." "For Wells has changed during his years in the mountains. He has become a Muslim. He finds the United States decadent and shallow. Yet he hates al Qaeda and the way it uses Islam to justify its murderous assaults on innocents. He is a man alone, and the CIA - still reeling from its failure to predict 9/11 or find weapons of mass destruction in Iraq - does not know whether to trust him. Among his handlers at Langley, only Exley believes in him, and even she sometimes wonders. And so the agency freezes Wells out, preferring to rely on high-tech means for gathering intelligence." "But as that strategy fails and Khadri moves closer to unleashing the most devastating terrorist attack in history, Wells and Exley must somehow find a way to stop him, with or without the government's consent."--BOOK JACKET.
