Marine sniper Kyle Swanson and his beautiful girlfriend, CIA agent Lauren Carson, are on a mission in Pakistan when their world is turned inside out. Kyle is captured and thrown in prison. Lauren is accused of being a double agent. The one person they can trust to help is the man who sent them on the black operation - Jim Hall, a legendary CIA agent, Kyle's sniper mentor, and Lauren's boss and former lover.

But Hall has gone rogue. He is selling America's innermost secrets to a ruthless Pakistani warlord who wants to mould al- Qaeda into a legitimate political party, and secure a nuclear arsenal. For Jim Hall, his former protégé Swanson is the final obstacle.

Caught in the sights of a man he once idolized, and who taught him how to shoot, Swanson must prevent a global disaster - from the streets of Washington to the Bavarian Alps, the two snipers stalk each other in a deadly hunt that has only one possible outcome.

Gunnery Sergeant Jack Coughlin was with the Third Battalion, Fourth Marines during the drive to Baghdad and has operated on a wide range of assignments in hotspots around the world. Donald A. Davis is the author of twenty-five books, including multiple New York Times bestsellers.
