Luna receives a letter from a woman in the small town of Millbrook, who describes a strange book she found on a library shelf in the summer of 1989. The book had no title, no author, and its pages were filled with a single, repeating word: 'Listen.' The woman, Nora, became obsessed with the book, carrying it home and reading it aloud, only to realize that the word was not a suggestion but a command. As she read, she began to hear things—footsteps in the attic, breathing in the walls, a voice that echoed her own words back to her. Luna reads Nora's letter aloud, her own voice growing hushed as she recounts the story, and ends with the unsettling detail that the book is now on her own shelf, and she's not sure when it got there.
