It's technically 'steampunk supernatural-fantasy period drama', but try the Parasol Protectorate series (the first book in the series is Soulless, and it's by Gail Carriger). Basically, the main character can turn off the magical abilities of anyone or anything she touches. The local supernatural creatures (ghosts, werewolves, vampires, etc.) do not like this one bit. I will admit that it is a bit heavier on the 'supernatural' part than the 'fantasy' part, but it's still a fun read. The first series takes place in the 1870s, and the sequel series (still being written) takes place in the 1890s.

There's also a spinoff series that takes place about 25 years before the first series, but it involves entirely different characters (two of them do show up in the main series as secondary characters, but that's it).
