It's a noir novel about minority oppression, from the first-person pov of a bareback who works as a sort of lawyer for those involved when lunes attack humans. When the book opens, she's slated to defend a lune who bit off a bareback's hand, and she's pretty sure it wasn't strictly an accident.
There's a romance, but this isn't a romance novel. If not for the werewolves, I would call it mainstream or suspense. It definitely feels noir to me. Anyway, it's definitely worth a look.
