One night, Ethan was jolted awake by faint sounds drifting from the hallway. Soft laughter. A child's voice. It sounded exactly like Lily. He rushed into the hallway. There was no one there. But it kept happening. Night after night. His parents began hearing it too — a child giggling in an empty room. Then one evening, Ethan came home to find Lily's old drawings scattered across the floor, and Zaarina lying in the middle of them. Every window was shut. His parents weren't home.
