September 1928. A young woman named Elodie checks into the Hotel Beaumont in Ironwood, Michigan, a town built on iron ore and silence. She is there to settle her great-aunt's estate — but the front desk clerk insists no great-aunt ever lived there. The room, however, is still hers: a narrow chamber on the fourth floor with a backgammon board already set up on the card table. Elodie plays a single game each night, against no one. The pieces move on their own. By the third night, she understands that her great-aunt is still there, and that she never checked out. Luna tells the story of a woman who learned to play a game she could never win, and what it cost her to keep playing. A story about inheritance, unfinished business, and the long silence between moves.
