Blood Demand by Kaylin Peyerk

No vampire has ever given a damn about me or my human family, that is until I was selected to become one.
Every one hundred and twenty-five years the four sinfully sexy ruling coven lords choose a new concubine from the human population. They hand pick a woman based on blood type, often looking for one with the rarest blood type in the world: AB-negative. Only .06 percent of the population carries it. To vampires it’s the holy grail, the city of gold. To human women, it’s a secret to be covetted, for the lords are known for their cruelty above all else.
To bad I was born with it. . . My blood is both gold and poison.
It was easy to stay hidden until my twenty-fifth birthday, but from that year forward every human on the planet is required to donate blood once per month. For me, that dreadful date is in two days. From that moment on I will be a helpless fool in their cruel game of cat and mouse. All I can do is resist their pull by fighting against them with everything I have. . .
Because as soon as the coven leaders have me locked between their bloodied hands, I know they’ll never let me go.
