The Free City - Unquiet Magic, #3

While the rest of Carlos Colosio's transformation from timid virgin to sexy satyr suits him just fine, things have gone too far when he starts growing a tail. To deal with the unwelcome development, he and Jack Belamit turn to the witch Anaksut, Jack's old nemesis, for help. While Carlos goes under the knife, the sorceress has a job for Jack: Track down the sexual vampire who is preying on men in the Free City of Helgenberg.
To conceal Jack's identity, Anaksut arranges for him to star in a porn video that is being shot in the neighborhood where the predator is active. To complicate matters even further, Jack's brother Rafe has attached himself to the investigation as Jack's sidekick. Who is the vampire stalking the Free City? How can Jack lure him into the open? And most importantly of all, can Jack avoid becoming the next victim?
