Grave Affairs by Lilith Daniels

Following an accusation of being a necromancer with no way to prove her innocence, Detective Kirani Kinsley Ramons turns in her badge and flees to Dragon Heights, Wyoming for a fresh start.
In Miami, few understand the difference between a necromancer and the descendant of dragons.
In Dragon Heights, nobody cares.
With weekly rains of unusual composition, dragon-kin and human alike vying for the right to become the next dragon in town, and magic lurking around every turn, there is no better place for Kinsley to hide her skills and history.
But when the local brothel workers are attacked and the bodies of would-be dragons begin showing up with alarming frequency, Kinsley revisits her past and makes the painful decision to hunt the hunter for the sake of her neighbors and new friends.
With her trusty carbunclo kitten at her side, she delves into the dark world of dragons and the city they call home to catch those behind the attacks before they can strike again.
What she doesn't know may awaken the sleeping beast, forever changing her destiny.
