To honor bonds forged twenty-five years ago at West Point, Lieutenant Colonel Sam Avery leads an illegal mission deep into ISIS-held territory.

An MH-47G Chinook helicopter departs formation in the Iraqi night. The mission is unauthorized. Success is unlikely. But to save a friend, Sam Avery and his crew of Night Stalkers have prepared for one last flight.

ISIS operatives in Tal Afar, Iraq, have captured American aid worker Henry Stillmont. Avery knows Stillmont as “the Guru,” the West Point squad leader who taught him about brotherhood, loyalty, and when to break the rules as a young cadet twenty-five years ago. Sam will risk his career and his life to save him.

As they near their target, Sam reflects on his time in the crucible of the United States Military Academy. West Point made Sam the leader he is. But his fellow cadets made him the man that he is. The ideals of duty, honor, and country have echoed throughout his life and drive him and his comrades as they undertake their final and most audacious spirit mission.
