It's late October, just after midnight, and Luna is sitting in Room 9 of the Blue Heron Motel on Hurricane Creek Road, trying to ignore the smell of mothballs and the sound of something moving in the attic above the ceiling tiles. She's here because her friend Marlene called her from this same room three nights ago, said she'd found something in the closet — a box of letters, all addressed to a woman named Evelyn, all postmarked from the same small town in West Virginia, all unsigned. Marlene said she'd leave the box under the bed for Luna to find, but when Luna arrives, the box is gone, the closet door is open, and the attic access panel in the ceiling is slightly ajar. What she finds in the crawlspace — a child's shoe, a wedding ring, a stack of photographs — tells a story that doesn't end with Marlene, and doesn't end with Evelyn either.
