Ouroboros

After avenging his alcoholic father's untimely death, Thomas begins his transformation into a cold-blooded killer. The Prakanis, a human race with superhuman abilities — and superhuman egos — rules the land of Xuelition with an iron fist, and as Thomas learns, it's much easier to work with than against them. When the government hires him to recover bonds from a disgruntled employee, Thomas has no idea what's in store for him. He's stealthy, clever, and one of the best assassins in the business, but what he learns on this mission will change his life forever.
