Better Off Undead by Cynthia Eden

Detective Jane Hart is just getting used to paranormal life in New Orleans. Monsters are real, and she’s the lucky cop who has to deal with them on a daily basis. Werewolves, vampires, witches, and demons—she has to face them all and keep their paranormal madness in check.

When a killer targets human men—and leaves their bodies scattered in local cemeteries—Jane suspects she may be looking at the crimes of a werewolf gone rogue. In order to hunt down the beast, Jane once again teams up with her werewolf lover, alpha Aidan Locke. But Aidan has been keeping secrets from Jane, dark secrets that will destroy her world.

Because Jane isn’t the hunter on her latest investigation. She’s the prey. And when a vampire attack leaves her helpless, the woman that Jane was before will vanish. She’ll become the one thing she fears most and Aidan…

Her fierce lover may have to become her executioner.
