He was the Western convert who would plunge deep inside al-Qaeda. He named his first son Osama after 9/11 and became a Jihadist. But then - after a sudden loss of faith - Morten Storm made a life-changing decision. He became a double agent and joined the CIA, MI6 and MI5.

Filled with hair-raising close calls and deception, Storm's story builds to the climactic finale when he must betray his friend and mentor al-Awlaki - al-Qaeda's biggest threat to the West. Storm is trusted to find al-Awlaki a wife from Europe. She becomes the bait for a possible American drone strike.
