When it comes to Esoteric Surgeons, Dorian Black is the best there is. Under contract for the organization known as Ziggurat, he's brought in to consult on an entity that haunts his memories. In an attempt to correct his past mistakes, he becomes both the hunter and the hunted, but that’s never bothered him. What really bothers him is the same question that’s been nagging him for years.
Who is this enemy?
Two mysterious objects may lead him to the answer he seeks. However, it's more than likely that the book with strange notations, and an even stranger watch, will leave him wishing that he never asked the question in the first place.
