Midnight Bites - L. K. Latham - Bog

A vampire, a werewolf, and a detective walk into a bar... They'll keep the peace, or leave in pieces.
CC thought she understood unhumans, but a new monster has moved into town. Even her unhuman friends are afraid. She needs more than her hunting skills; she needs a team to catch it before it kills, again. Luckily, she has one: a couple of old vampires with scores to settle, a werewolf or two with attitude, and a few friends with the police.
She'll keep the team working together, but only if she can keep them from killing each other.
No matter where she turns, she feels the monster getting closer to her. The closer it gets, the sharper her senses, until she realizes she and the monster are alike: Each sees souls and each sees the other's soul. Even her friends are worried about her.
Is she strong enough to save herself when she can't even save the one she loves?
