It's late autumn, just past midnight on a two-lane highway through the Ozarks. Luna picks up a single passenger at the Canyon Motel — a man in a worn denim jacket who doesn't speak, doesn't blink, and smells of wet stone. As the bus winds deeper into the hills, she notices his reflection in the rearview doesn't match his face: his mirror-self is younger, smiling, a woman's hand on his shoulder. She tries to rationalize it — a trick of the glass, a bad angle — but the bus's interior lights dim each time she checks. By the time she pulls into the next depot, the passenger is gone, his seat empty except for a small grey stone that looks like it was shaped by water, not by hand. Luna keeps the stone in her jacket pocket. Some nights, she swears it's warm.
