The book tells of a world that survived a catastrophe, where the main character—a monster hunter—is forced to cooperate with a monster. He trained in the Order of Masters and now fights otherworldly beings, helping to restore the world. However, circumstances compel him to join forces with the one he must destroy—namely the Monster itself. In a world where light and darkness are constantly at war, Grayden and the Monster end up at the center of events, and they have to decide whether their alliance has a place to exist.
