Katrina Dobra is a sensitive girl in an evil world where everyone takes advantage of her, until she goes to a party in Las Vegas and meets the noble Mikael Blake, an intimidating yet attractive man with hypnotic grey eyes that offers her an irresistible new life with him. Katrina feels in heaven, until she finds out that her boyfriend is the devil. Her initial fear and rebellion against him are useless, because Mikael is the King of Vampires and his pleasure is the pain of his new slave, Katrina, that loves him so much for the powerful emotions he makes her feel that wants to learn to bear his tortures, hoping that one day he will free his good part just for her.

Author's note: no, the vampire won't become the cute puppy of the main character.
