"One year ago, Captain Jake Mahegan led a Delta Force team into Afghanistan to capture an American traitor working for the Taliban. The mission ended in tragedy. The team was infiltrated and decimated by a bomb. An enemy prisoner was killed. Mahegan was dismissed from service--dishonored forever. Now, haunted by the incident, Mahegan is determined to clear his name. The military wants him to stand down. But when the American Taliban returns to domestic soil--headed by the traitor who ruined his life--Mahegan is the only man who knows how to stop him. Outside the law. Under the radar. Out for vengeance..."--Amazon.com.
