In the autumn of 2019, Luna's cousin Ezra took a job mending fence along the old county line road in Barrow County, Tennessee — a stretch of barbed wire that had stood since the 1870s, marking nothing but a boundary no one remembered. The fence posts were cedar, hand-cut and hand-set, and every third one bore a mark like a pair of crossed bones. Ezra worked alone, dawn to dusk, and he said the fence never ran straight. It curved, it doubled back, it crossed itself in places — as if the land had been measured by a man who kept changing his mind. The farmer who hired him, a man named Hollis, warned him not to walk the fence after sundown. Ezra didn't listen. Now he lives in a town that isn't on any map, and the only way I can reach him is by driving that county line road at midnight, counting the posts. But the posts keep moving. And the road keeps getting longer.
