On a remote cliff overlooking a restless sea stands a lighthouse unlike any other. It does not shine beams to guide ships but instead counts hours breaths and memories shaping the rhythm of lives around it. When Mara a young woman burdened by a slow watch arrives to take her place as keeper she expects only oil lamps and glass. Instead she discovers shelves of jars that contain captured moments of time itself each pulsing with destinies past present and still to come.
