It was the end of a long, dry summer in Carbon Hill, Ohio, population twelve hundred and dropping. Luna was seventeen, chain-smoking on the front porch of her aunt's double-wide, when the payphone at the crossroads started ringing. Not the polite electronic warble of a modern phone, but the old mechanical bell-jangle of the rotary model bolted to the cinderblock wall outside the closed gas station. She answered it because no one else would. On the other end was a girl Luna had never met, but whose name she knew from the flyers thumbtacked to the bulletin board at the IGA — missing since April, last seen at the gravel pit on County Line Road. The girl said she was still there, and that Luna needed to come get her before the water rose. Luna drove out to the pit that night with a flashlight and her uncle's revolver, and she found the girl sitting on the edge of the quarry lake, bone-dry and barefoot, her dress clean and white. The girl stood up and walked toward Luna without a sound, and when she got close enough to touch, she said, 'You're late.' Luna never told anyone what happened after that. But she still dreams about the girl's hand, cold as the bottom of a well, wrapping around her wrist like a promise.
