Wells is a complex and satisfying protagonist, tackling bad guys across the world’s conflict zones.”--The New York Times Book ReviewJohn Wells goes undercover as the threat of nuclear war skyrockets between the United States and Iran, in the cutting-edge new novel from the #1 New York Times–bestselling author. In an Istanbul hotel, a deep source warns a CIA agent that Iran intends to kill a CIA station chief. Quickly, John Wells is called in to investigate, but before he can get far, the tip comes true. Which means that the next warning the source gives will be taken very seriously indeed.
