Brad Thor, the New York Times bestselling author of Takedown, delivers an explosive international thriller featuring Navy SEAL turned Homeland Security operative Scot Harvath, who somewhere, somehow, has left the wrong person alive.

"Thou shalt not negotiate with terrorists..."

Six months ago: In the dead of the night, five of the most dangerous detainees in the war on terror are pulled from their isolation cells in Guantanamo Bay, held at gunpoint, and told to strip off their orange jumpsuits. Issued civilian clothes and driven to the base airfield, they are loaded aboard a Boeing 727 and set free.

Present day: Covert counterterrorism agent Scot Harvath awakens to discover that his world has changed violently -- and forever. A sadistic assassin with a personal vendetta is wreaking havoc of biblical proportions. Unleashing nightmarish horrors on those closest to Harvath, the attacker thrusts everything Harvath holds dear -- including his life -- into absolute peril.

Ordered by the president to stay out of the investigation, Harvath is forced to mount his own operation to uncover the conspiracy and to exact revenge. When he discovers a connection between the attacks and a group of prisoners secretly released from Guantanamo, Harvath must ask himself previously unthinkable questions about the organizations and the nation he has spent his life serving.

A renegade from his own government, Harvath will place his life on the line as his search for the truth draws him into a showdown with one of the most dangerous men on the face of the earth.

Brad Thor roars through this nonstop adventure full of international intrigue, twisted betrayals, and ultimate revenge.
