In a universe where Magic and Technology exist as one, there is only one rule - the survival of the fittest. In the first novel, Assassin's Vendetta, Matherion, as a teenager, horrifically watches his father get shot killed, older sister get raped and shot as well, and then watches his mother go through the metahuman transformation only to die. Attempting to survive on their own, he sees his younger sister shot by a rivaling gang member on their way to find jobs. With boiling rage inside him, a Duke persuades him to enroll into a secret assassination academy. Ten years passed and after his final studies, he becomes released from the academy to receive his first hit job, but each time he notices a woman awfully looks like his younger sister. Once he realizes that she is alive, he attempts to get out of the entangled web of crime, but can he escape with his sister without running into another assassin or interference from the Duke?
