The Endgame

The global operation is underway, and the stakes have never been higher. From the command centers in the Pentagon to the hostile dirt of foreign soil, every member of the original Guardian Corps has a critical role to play in a mission that spans multiple theaters of operation. As the shadowy organization's true power is revealed, Lt. Gen. Allison Cole faces a soul-crushing dilemma: she must choose between the success of the mission and the lives of the soldiers she has mentored for over two decades.

The cost of courage is demanded from everyone. CW2 Alex Chen is thrust into a mission that requires a final, devastating sacrifice to save his team, while First Sergeant Thompson and Major Walker must navigate a moral minefield that puts their careers—and their lives—on the line. In a climactic battle that brings units from every corner of the globe together, a secret from the past threatens to tear everything down. The mission is a success, but the Guardian Corps will never be the same again.
