Mystic Ink, by Casey Wyatt

Welcome to Mystic, Connecticut, where a Satyr owns the local pawn shop, a Minotaur serves the tastiest pizza in town, and the nearest gate to the Underworld resides in the alley outside a tattoo parlor.

Nix – Sea Nymph, talented artist and proprietor of Mystic Ink –  just wants to run her tattoo shop in peace and quiet. Peace and quiet, however, are the least of her problems. Mortal corpses keep springing up in her alley like daisies.  Hades is angry that the mortals’ souls are missing. And to top it all off, the human authorities suspect Nix of foul play.

Before long, the supernatural police force, takes an interest. They dispatch Agent Calder Quinne to investigate.  His assignment is simple: determine Nix’s guilt or innocence by observing her daily routine. Instead, he’s faced with an uncooperative Nymph who resents his presence and evades him at every opportunity.

Nix finds Cal far too attractive and a challenge to her self-imposed ban on relationships. She wants him out of her life as soon as possible. When Cal’s soul is stolen next and Nix wakes up missing memories of the evening’s events, even she starts to wonder if she’s guilty. Now, she has only two weeks to locate Cal’s missing soul, or he’ll be doomed to spend eternity as a Shade.
