Obsidian Murders by Nicole Brona

SPFBO10

A journalist who's kinda weird. A 500-year-old vampiric detective. Two young women dead from an unknown, magical source. 
Tessa O'Hara is tired of people thinking she is crazy. Growing up sensitive to the supernatural and deemed mentally unstable by every therapist she’s ever seen, Tessa moves to Washington D.C. to start fresh. But when there are two murders in her neighborhood that reek of magic, she's a bit freaked out and utterly regretting her decision to become a semi-functioning adult.

Seeking aid from a vampiric detective, a grumpy house faerie, and several local Wiccan covens, she is determined to use her abilities to help. But Tessa and her new friends are at a loss when the case abruptly goes cold with no leads or suspects.

Can Tessa help find the killer before another woman is found dead?

Obsidian Murders is the first book in the all slaying, no laying Midnight Detective Agency urban fantasy series. If you enjoy a sassy main character, magical sidekicks, and puzzling mysteries, then you will love this novel.
