Some bloodlines are not inherited. They are hunted.
Salem, 1693: as witch-hunt hysteria tightens its grip, a young wife named Elspeth becomes the target of something far older than fear. Marked by a demon's vengeance and condemned by the town that should have protected her, she dies carrying a curse that refuses to burn with her.
Three hundred years later, twin girls are born in London-and immediately torn apart. Eliza is raised in love, protected from the truth of her origins. Eloise grows up unwanted, watched over by a darkness that whispers, encourages, and waits. Though separated by an ocean, the sisters remain bound by a brutal psychic connection: every act of violence Eloise commits tears through Eliza, body and soul.
As Eliza follows the trail to Salem, she discovers that some monsters are made, some are born-and some are family.
