Blood & Sex: Michael by Angela Cameron

This is an original spine-chilling and sexy a tale of a Mafia vampire and the detective who is determined to bring it to justice...Detective Victoria Tyler is investigating Collins Bay's new serial killer, one of the city's vampires. Since they have marked her as a human to be killed or conquered, Tori knows that Michael is her only hope for survival. But she hasn't spoken to him since the night she tried to kill him. As the enforcer for the Italian vampire cosca, Michael expects a certain amount of cooperation from his boss. That amount has been shrinking ever since their leader took a new sadist lover. So when the detective requests his help, it's just the excuse he needs to take control of the city and the delicious human.

Risking it all, Tori agrees to let Michael take her neck and lead her on a journey through a world of bondage, domination and blood to stop the killer. But can she resist the dark lusts he sparks? Or will her weakness get someone else killed?
