In the autumn of 1927, a young woman named Clara disappeared from a dance marathon in the small town of Millbrook, Indiana. The marathon was held in the old Grange Hall, where couples danced for days on end for prize money. Clara's partner, a stranger in a cream linen suit, was seen leading her off the floor and out the back door. No one remembered his face. Luna tells the story of the night she found Clara's brooch in the dust of the abandoned hall, and the whisper of a waltz that still plays at three in the morning. A story about the things we chase, the things we lose, and the empty chairs we keep spinning for.
