They promised to only use his lethal skills for good. But in the Syrian desert, doing good requires doing something very, very bad.

Ex-CIA ghost Jonathan Hunt has made a pact with his wife, Rosa: his days as a government weapon are over. From now on, they operate by a new code—stepping in as off-books samaritans for those who have nowhere else to turn. Rosa even wants Jonathan to train her so she can fight by his side in the shadows. But Jonathan knows the toll the darkness takes, and he’s deeply hesitant, desperate to protect her from the blood-soaked life he barely survived.

Then a horrific video surfaces, and the rules change.

An old humanitarian friend of Rosa’s has been brutally tortured and murdered by a ruthless terrorist faction in Syria. The extremists have seized a remote town, using innocent lives as a human shield while they build a sprawling network of terror that international military forces are too paralyzed by bureaucracy to touch.

Bureaucracy dictates inaction. Jonathan and Rosa dictate terms.

Deploying to the war-torn desert as a two-person asymmetrical strike team, they aren't there to negotiate. They are there to dismantle the syndicate from the top down. But as Rosa steps onto the battlefield for the first time, Jonathan must face his greatest fear: that in order to save a town and avenge a friend, the woman he loves might have to become just as lethal as he is.
