The Vampire Vivienne
By Karen E. Taylor
Series: Vampire Legacy

Fifth book in the Vampire Legacy series. "Allow me to introduce myself. My name is Vivienne Courbet, and I've been a vampire since 1719. Let me assure you that I don't look a day over twenty-nine. You're probably more familiar with my blood sister, Deirdre Griffin, but she's on holiday right now so I thought I'd take center stage and tell you my life story.

You see, war has been declared against the Cadre, and a close friend of mine was among the first fatalities. I must out an end to this rebellion before I lose anyone else.

My handsome human lover, Dr. John Samuels, will assist me in my efforts -- and anything else I should need. As of yet, I'm unsure if our enemies are human or vampire. But when I find out, I vow that blood will be spilled..." (from karentaylor.com)
