The monster of Elendhaven
(Book)

The city of Elendhaven sulks on the edge of the ocean. Wracked by plague, abandoned by the South, stripped of industry and left to die. But not everything dies so easily. A thing without a name stalks the city, a thing shaped like a man, with a dark heart and long pale fingers yearning to wrap around throats. A monster who cannot die. His frail master sends him out on errands, twisting him with magic, crafting a plan too cruel to name, while the monster's heart grows fonder and colder and more cunning. These monsters of Elendhaven will have their revenge on everyone who wronged the city, even if they have to burn the world to do it. -- from Amazon.
