Something is wrong with Unity Command, and Cullen can feel it in his bones.

The tactical powerhouse that helped shift the momentum of the war is under immense pressure from the Unity Alliance to end the war with a resounding victory. Plans and operations feel panicked, reactionary, and fragmented. As he continues to carry the banner and march forward against the enemy, Cullen begins to question his superiors—and his future.

The galaxy burns. The fog of war thickens.

Tensions at home and abroad are a powder keg poised to ignite. When the enemy launches a surprise attack on the Shining League colony of Angkor, they don't destroy it—they occupy it. Unity Command is stunned. This drastic change in the tactics of the enemy is unprecedented and requires a swift and decisive response. The liberation of Angkor is anything but a textbook assault. The mission quickly goes off the rails with devastating consequences that will forever change the Unity Marines Corps, and Cullen Bright.

Because the Hardshells are victims of war themselves, and they're fleeing an enemy that will change organic life forever.

The Haiksos have conquered galaxies, permanently altered numerous species through heinous genetic experimentation, and spread their malevolent influence from system to system with brutal efficiency. Their galactic manifest destiny proves them to be a bigger threat than the Hardshells, and one that humanity is woefully unprepared to defend against.

To counter this new threat, the Gold Medal Marine will have to make a tough decision; one that could possibly mean the end of his military career—if he survives.

The writing duo of JN Chaney and Terry Maggert that brought the bestselling and Dragon Award nominated series Backyard Starship returns with Book 3 of Gold Medal Marine, a no-holds-barred Military Sci-Fi series that will take you from the Olympic circle to the frontlines of a Marine Special Operations Team as they fight a brutal war where failure doesn't mean the end of the war—it means the end for humanity.
