I enjoyed it. Kind of a steam punk fantasy horror sort of thing, with a nice spin on werewolf tropes. The strong female heroine is very well written as a grumpy teenager accidentally figuring out she has very strong magic powers. Good relationship with her crazy mom stuff that made me laugh.
The thing that qualifies this as horror, however, is not the werewolf element. It’s the terrible mad scientist emperor, and what he is doing with his limitless resources and boredom. Once I got to that part, I really could not put the book down, and finished the last third in a big sprint one night.
