In the small town of Midden, Iowa, the diner stayed open through the night the sky turned the color of bone. A man walked in covered in fine gray dust, his coat stiff with it, his eyes red-rimmed. He ordered black coffee and a slice of apple pie, and he told Luna he'd been driving for hours through the ashfall—but the weather reports said nothing about ash. As he spoke, he never blinked, and his hands trembled when he touched the mug. The longer he sat, the more Luna noticed things were wrong: the dust on his collar didn't brush off, the pie sat untouched, and outside the window, the streetlight flickered on a road that didn't seem to end. In the morning, there was no ash, no tire tracks, just a single coffee cup on the counter, still warm.
