This is New York Times bestseller Alex Berenson's eighth gripping spy novel featuring ex-CIA agent John Wells.

At an Istanbul hotel, an informant tells the CIA that Iranian forces intend to kill a station chief. Ex-CIA agent John Wells, an expert in the Arab field, is summoned in to investigate, just as the tip comes true. So when the source warns of a radioactive package on a ship bound for the United States it's imperative he's taken seriously.

As the threat rises and the government springs into action, something doesn't feel right. Sent on a private mission from Guatemala to Thailand, Hong Kong to Istanbul, Wells must now use every skill he has to hunt down the threat.

Because soon it may be too late to pull the United States back from the brink of war. Can John Wells succeed where all others have failed?
