If you're fighting immortals who always get back up, you'd better have a way to do the same thing. Otherwise, it's lights out... When you're a soldier genetically enhanced to the point of near immortality and you fight a mortal soldier resurrected with the pilfered blood of your people, friendship never enters the equation. But what if the enemy you despise holds the key to your salvation? Includes prequel novella and two full books. Think Enemy Mine meets Lethal Weapon on a deserted, sci-fi world.
