Unknown to humans, vampires walk among them. But there are two kinds; the "bittens" and the "borns." The Born ones have families much like humans, and are good, civilized people. However, the bittens are another story, and it is up to the borns to do what they can to keep the bittens under control. When Ella, a human girl, encounters both kinds, her world is turned upside down. And when it's discovered that she has unknown assets of her own, things get very interesting indeed.
