Skinwalker (2009)

"Jane Yellowrock is the last of her kind--a skinwalker of Cherokee descent who can turn into any creature she desires--and hunts the undead for a living. But now she's been hired by Katherine Fonteneau, one of the oldest vampires in New Orleans and the madam of Katie's Ladies, to hunt a powerful rogue vampire who's killing other vamps. Amidst a bordello full of real 'ladies of the night,' and a hot Cajun biker with a panther tattoo who stirs her carnal desire, Jane must stay focused and complete her mission, or else the next skin she'll need to save may be her own."--p.
