To unmask a CIA mole spying for ISIS, John Wells must return to his roots and go undercover as an Arab jihadi - and hope he can survive it - in the new cutting-edge novel from the #1 New York Times-bestselling author. It is the most dangerous mission of John Wells's career. Many years before, Wells was the only American agent ever to penetrate al Qaeda, but times have changed drastically. The terrorist organisations have multiplied: gotten bigger, crueller, more ambitious and powerful. Wells knows it may well be his death sentence. But there is no one else.
