Awakening the Fire — Ally Shields

A witch with a badge and a gun...and her first murder case.
 
Arianna Calin has sworn to keep the peace in Riverdale. Most of the Otherworlders haunt the Olde Town district--partying at vampire strip clubs, dining in elegant supper clubs, and inhabiting the cliffside caverns along the Mississippi. They're really no trouble at all...until something goes wrong.
 
Being a cop for the supernatural is a tough job, but someone's got to do it. Ari carries a gun, a wicked-looking dagger, and a few magic charms against things that go bump in the dark. She's also a fire witch--an ability that comes in handy, since her cop partner Ryan is only human.
 
When a virtual reality drug hits the streets, people start to die, and an elusive pack of werewolves shows up at every turn. So does the aristocratic vampire singer, Andreas, with his Old World charm and his spellbinding voice.
 
Ari and Ryan are drawn into a web of murder and evil. While the city simmers around her, Ari scrambles to prevent an all-out supernatural war...
