"A Lycanthrope is killing vampires and scattering body parts across town. Much to the police department’s displeasure, private investigator Mina Black gets involved. Her newest client is a member of the Vampire Council and has asked her to look into the murders. Little does Mina know, she has won the attention of the werewolf, and he’s bent on adding her to his list. Mina’s determined to uncover the Lycan’s identity, even if it kills her. But things are never that easy. Add a hate group, vampires, new cravings, the fear that her lover is the killer, and she’s up to her neck in trouble again." (from Amazon.com)
