In the summer of 1989, a teenager in the small town of Millbrook, Ohio, takes a dare to spend the night in a house that has stood abandoned since the 1950s. The house on Cedar Lane was once home to the August family — father, mother, and two daughters — who vanished without a trace one autumn night. Locals whisper that the house remembers them. That it replays their last moments alone, over and over, like a record caught in a groove. The teen, a girl named Ellie Marchetti, brings a flashlight, a notebook, and a tape recorder to document the truth. What she finds is not ghosts in the usual sense. It's something quieter. Something that waits in the walls, in the wallpaper, in the way the floorboards creak in a pattern that sounds like footsteps walking in place. Luna tells the story as Ellie told it to her, years later, in a diner off Route 23. Ellie still carries the scar on her palm from the nail she grabbed when she tried to climb out a window. She still cannot look at floral wallpaper without her throat tightening. This is what she heard that night.
