Two hundred years ago, aliens invaded Earth. A violent war followed. The enemy won. Some of us escaped, most of us didn’t. On Proxima they flourished - the invasion forgotten. On Earth we floundered - the horror began. Their world is advanced, peaceful, and secure. Our world is broken, savage, and overrun. A new invasion is coming. A hunger that has swallowed half the universe. They don’t care which planet we live on. They want to end us all. But where there is life, there is hope. And where there is hope, there are heroes. This time, vengeance will be ours.

Earth. After the invasion. The planet is in ruins. Humankind struggles to survive. Hayden is a Sheriff in a world without law. A good man in a world gone bad. He knows the fallout of an alien attack when he sees it. He's never seen anything like this before. Isaac is a Marine in a world without order. A good man with troubles of his own. His mission was to protect the innocent, including his son. Instead, he's the only survivor.

The invaders are gone. Earth is in ruins. The strong prey on the weak. In the wastelands of what’s left, a lone gunslinger delivers his own brand of justice. Some call him lawman. Some call him madman. Some call him vigilante. Some call him killer. Some call him legend. They all call him...the Sheriff. This is his story.

The enemy is coming. The enemy is already here. For years they’ve prepared, plotted, and planned. For years they’ve waited to strike from above and below. Earth is under siege. The enemy covers the landscape. Proxima is unharmed. But that’s about to change. No armies can stop this menace, and no defenses can slow the advance. We are scattered and isolated. We are ignorant and weak. No help is coming. No help remains...or does it? Old heroes will sacrifice everything. New heroes will rise.

Raised fatherless in a galactic Brinktown, Joe Pikeman only ever wanted to escape. The Galactic Guard offered that escape, with the promise of regular meals to boot. Now Joe is a full Guardsman, with his own ship and a snide partner bot who hates humans almost as much as he hates other bots. To the pirates he hunts, Joe is known as the Butcher. His bloody reputation has landed him in the center of a sweeping conspiracy that threatens to stamp out the galaxy’s last surviving human settlements.
