Sixteen-year-old Tierney James lives in a misogynistic community in which young women are accused of possessing a magical power to seduce men through a powerful aphrodisiac they emit from their skin. They are therefore exiled out of the community for one year, called the Grace Year, to release their magic into the wild before the survivors come home to marry. Outside the compound walls are poachers who rape and kill the girls and sell their body parts for profit. Tierney is banished from the newly formed Grace Year clique of girls and falls for a young poacher whose own life is threatened. But between the compound and the hunters, the greatest danger may come from the other girls on their Grace Year.
