The Key of Cobblestone and Bone

Dan MacLean thought his ghost tours were just a gig, a way to pay the bills with cheap scares and bad jokes. But when a mysterious woman with storm-dark eyes starts stalking his tours and his audience members start turning up dead, he's dragged into a hidden Edinburgh where Fae courts stir and ancient predators hunt. The worst part? Dan isn't just a witness; he's the prize. He is a living key, and Death herself has a vested interest in who turns the lock.
