Now a new threat faces his team: a demon with bullet—and bite—proof skin, which can’t be stopped by ordinary means. John’s only solace comes in the form of his lovers: Caleb Jansen and the vampire spirit Gray. Caleb and Gray have their own problems, however. Unbeknownst to John, they’ve been tracking a mysterious entity across the city. And after they finally come face to face with their quarry, nothing will ever be the same.
