In The Vampires among Us by Thaddeus Romans
In the movie "Underworld" the character of Selene, played by Kate Beckinsale, answers to no one but the master vampire Viktor. However, in the end she made her point with him. A little joke, so to speak. But it is no joke for mortal men who find themselves in a relationship with a female vampire. Physically she is his master, but so too is she an emotionally. The female vampire has been alive for hundreds of years and gained experience and relationships with men, and the knowledge of power and how to use it.in the vampire novel, Unholy Embrace, Nessa, the vampire, is completely in control of her mortal lover Frank. He puts up a spirited battle to have a more equal relationship, but she is always two steps ahead of him. Only her love for him, which creates a vulnerability, gives him any leverage in the relationship. This is more than can be said of almost all relationships between female vampires and mortal men.
