Blood Oath (Belt War Book 1)

Recruited.
Convicted.
Augmented.

Kevin Collins is no ordinary hero. Two decades with the Belter Cartel saw to that. They took him as a kid. Pumped nanotech into his veins, and turned him into a human weapon. They made him unstoppable...

And then the law caught up. Sentenced to hard time on a prison planet, Collins swears he's done with fighting. He only has one goal: to see his daughters again. Nothing can stop him. Except, maybe, an alien invasion.

But he's about to find out that the invasion is no accident. Whatever's in his blood, the aliens can sense it. And they're coming for him.

It's time to fight, or die.
And Collins ain't finished living...
