Book 2 in the Protective Affairs series. Serena Blackwood can't believe it when she learns she's becoming a vix. Finding that she has to work with sexy vampire Marcus Castillo to catch a rogue vampire only adds to her stress. She's unbelievably attracted to the hunky man but knows staying near him will increase the chances of her jumping his bones--and Marcus discovering her secret. Marcus knows the witch working with his team is hiding something. She's beautiful and talented and he wants to know the mysteries she's hiding almost as much as he needs to know the feel of her body moving against his. But the rogue has plans of his own and unless Serena and Marcus work together, they could lose everything
