Eighteen-year-old Valentine Shapiro got a raw deal in the parent lottery. Her father was part incubus demon, and her mother's never forgiven her for that. Thrown out of the house by her mother, Val does the only thing that seems to make any sense—she takes aim at the town vampires. A stake a day keeps the demon at bay. Soon enough, she finds herself deep in the underbelly of the city, discovering the secrets of the Demon Underground with the help of her faithful hellhound, Fang, and fighting to save those she loves. Whether they love her back or not.
