This is book number 4 in the Jane Yellowrock series.
The vampires of Asheville, North Carolina, want to establish their own clan, but since they owe loyalty to the Master Vampire of New Orleans, they must work out the terms with him. To come up with an equitable solution, he sends an envoy with the best bodyguard blood money can buy: skinwalker Jane Yellowrock.
But when a group of local campers are attacked by something fanged, Jane goes from escort to investigator. Is it a rogue-vampire, shapechanger, or witch? Or something else magical? Unless she wants to face a very angry master vampire, she will have to work overtime to find the killer. It's a good thing she's worth every penny.
