Cora Medville, the owner, seems welcoming enough, but soon the creepy house and its inhabitants are urging Lucy to flee, or risk dying like some before her. Four decades earlier, runaway Cora is smitten by Arcania and the dashing owner Harlan. Craving a sense of belonging, she finds it with her new family and their majestic mansion. But when residents start disappearing and she learns the terrifying truth, who can she trust? How far will she go to protect Arcania's sordid secrets?
