He’s gone behind enemy lines countless times before. But this time, he’s going alone.

Foster Quinn is more than a former Force Recon Marine. He’s a husband. A father. A faithful brother to his teammates. When one of them is killed during a high-risk operation to track down a dangerous arms dealer, Foster struggles to balance his roles as a dedicated family man and an elite warrior. Despite his inner demons—or maybe because of them—Foster can’t walk away from his brothers.

Then he gets the chance to step in where his best friend left off, assuming a cover identity in Iran that will get him close to the arms dealer and pave the way for a critical mission. On his own in a new country, he must carefully choose who to trust. An Iranian taxi driver. An American hunter. A British oil executive. One wrong move could spell disaster. Not just for the mission, but for Foster.

The clock is ticking. A team of tier-one warriors is set to plummet through the night sky in enemy territory. They’ve trained for this. But their success hinges on just one man.
