Hunting Ground by Patricia Briggs

Anne Latham is still getting used to being a werewolf. Never mind throwing into the mix the fact that she's an Omega (outside the normal pack structure with powers of her own). And she just was mated to Charles Cornick who is the son of the most powerful werewolf in the Americas. And Charles, his father's enforcer, is no slouch. That's the reason why Charles, instead of his father, is the one to attend a meeting of Alphas from around the globe to discuss whether or not werewolves should make themselves known to the human population.
Also attending is a man known as "The Butcher," a long-loved werewolf from France who loves to kill. Innocents are his favorites and he may have set his eyes on Anne. Someone certainly has since she's set upon by six vampires while shopping. It all gets hairier when the wife of a werewolf who believes he's King Arthur reincarnated is attacked. Through in a fae who used to be Charles' lover and it all gets very, very complicated.

A fine story that does a lot to advance what's going on in the larger Mercy Thompson universe.
