Wolftown

Private Investigator Jae Kim primarily works in places most humans won't go: Wolftowns, the walled neighborhoods within America's largest cities where werewolves and many other shifters live. The work has been routine for five years, ever since he broke up with his boyfriend Czoltan and moved to Chicago, but when an old Army buddy resurfaces in his life and instigates an uncomfortable reunion with Czoltan, Jae's life is going to get a lot more complicated--and not just because Czoltan is a werewolf. Jae's going to be thrust into the front lines of a battle between shifters and a shadowy foe, one he's not prepared for but can't exactly back out of now.

And did I mention ghosts? There's ghosts, too.
