Prometheus Graft: The Slayings at Death's End #1

George Northy and Caitlin Yarsky open a gothic whodunit starring literature’s most famous man-made monster. Decades after his creation, Frankenstein’s creature has rebuilt himself as Prometheus Graft, a refined detective whose scars have faded and whose intellect has tamed his brute strength, though he remains not entirely human.

At the dawn of a new, scientific century, Graft is called to Death’s End, a remote Romanian castle where an undying lord has gathered Europe’s supernatural powers to negotiate peace. When an envoy turns up dead in the hedge maze, witches, werewolves, vampires and ghouls turn on one another, and Graft must find the killer before sunrise brings open war.
