Act of Treason

In the fourth novel in the New York Times bestselling 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.
