An Act of Treason

In the fourth audiobook in the New York Times best-selling series, Marine sniper Kyle Swanson finds himself in the sights of a man he once idolized - a true American hero turned traitor.

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 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 mold al-Qaeda into a legitimate political party and secure a nuclear arsenal.

For Jim Hall, his former protégé, Swanson, is the final obstacle. Success or failure pivots on whether Swanson can stop the old friend who trained him to be a shooter. 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.
