Luna recalls a winter night in Bitterwater, Texas, 1983, when her grandmother's antique porcelain mantel clock began to run backwards. Each night, the clock's chime counted down instead of up, and the hands rewound time itself—one hour, one day, one month. As Luna's grandmother faded into the past, the clock showed her a version of the house that no longer existed, with a woman at the piano who played a song Luna had never learned. A quiet, devastating story about memory, loss, and the things we cannot stop.
