After a whirlwind romance, Evelyn is excited to start her new life with her husband, Peter. But when the sudden passing of Peter's father gives him the title Lord Black, along with the family's remote manor, Blackthorn House, she finds herself in the middle of the wild Yorkshire Moors, separated from the only life she has ever known. She quickly realizes something is wrong with Blackthorn House: children's laughter can be heard throughout the halls, the constant fog is full of wailing specters, and her dreams are haunted by an entity wearing her mother's corpse like a suit. Furthermore, her new husband has become a stranger to her, treating her with barely veiled disdain. Under the constant surveillance of the staff of Blackthorn House, Evelyn struggles to find answers. Unable to gain any insight from the frightened locals in the nearby village, Evelyn and her trusted servant, Lilly, must seek answers from the dead. They learn that the Black family has long kept a dark and terrible secret. A secret that threatens both of their lives and, now, the life of Evelyn's unborn baby. A secret involving a bargain paid in blood.
