An elite warrior. A double agent. A conspiracy that could burn the world to the ground.

David and Natalie Shaw have hunted traitors, dismantled shadow empires, and walked away from wars no one would admit were being fought. But when an allied operative turns on them, the result is a coordinated strike that cripples the West's most elite warriors—and shatters the Shaws' lives.

Faatin Radi served the Crown at the highest levels of Britain's military and intelligence services. But after uncovering a life-changing truth, he's armed himself with nuclear weapons, a vendetta that spans generations, and the intent to strike the United States' most revered strongholds. With allies compromised and enemies hiding in plain sight, Shaw and Natalie must pursue him across Europe, the Middle East, and the storm-tossed waters of the Mediterranean before the unthinkable happens.

Every step brings them closer to the center of their war against a hidden council acting as puppeteers, instigating global events, and pulling the strings of nations. And in a game where loyalty is a liability, the price of losing is a world left defenseless.
