HERE from Smashwords.
When Niah awakens in a morgue, covered in plastic, he can’t remember anything. As he tries to escape, he's captured and told that he's no longer the same. He's not just Niah anymore.
In fact, he’s the first to survive an experiment that infused him with alien DNA.
How is irrelevant. Why is unthinkable. And he's not alone. When another man is transformed, Niah decides they will act like they conform. They will learn everything they can about the aliens...and then take their planet back.
