Tokyo, 2013. An ordinary high school girl. An ordinary life. Nothing about her suggests she was ever meant for anything more. Then a storm rolls in-and something that has been waiting inside her chest for years finally opens its eyes. Possessed by a centuries-old devil with a three-hundred-year-old obsession, she is dragged into a world she never believed in. Cursed souls. Haunted locations. Things that move in the dark that have no business being there. A supernatural teenage group finds her before she completely loses herself-and what begins as an uneasy alliance slowly becomes the only thing standing between her and everything hunting her. But the deeper they dig, the darker the truth gets. Because the devil inside her isn't the most dangerous thing she's carrying. And then there is him. The boy who already knew her before she knew herself. The boy who carries a secret older than either of them-one that doesn't just connect them but was always going to. No matter what. No matter how long it took. Something else had been searching for her the moment she was brought to the world. Waiting to hunt. Waiting to devour. It just found her. The door is open. And the dead don't wait.
