When Mariya inherits her grandmother's dilapidated cottage in the isolated, fear-choked coastal town of Blackwater Bay, she dismisses the local whispers about a vengeful witch. But then she discovers a silver, moon-shaped locket hidden in the wall.Once worn, the artifact does more than cling to her skin-it unlocks the consciousness of her powerful, malevolent ancestor, Elara Vestia. Mariya finds herself losing control, her body acting out brutal, ritualistic acts under the influence of the cold moonstone. As the town's fear turns to violent hatred, Mariya must use the witch's own terrifying powers against her, knowing that to break the ancient pact, she may have to sacrifice her own soul.
