Sisterhood runs blood-deep. Ashley, Miranda, and Vangelica are typical sisters. They'll fight, tease, and blackmail each other, but when someone threatens their sisterhood, the fangs come out. The question is, when their crazy Aunt Carrie shows up in the form of girl next door Mia, will their trio become a foursome, or will It be all-out war? Because these vampires know meals may come and go, but sisters are forever.
