Fourteen-year-old Lira is a repair genius at her grandfather's shop, "Yesterday's Fix." When she mends a strange music box, it doesn't play a tune—it reveals ghostly echoes from the past. The box is a "Chronos-Knot," and it exposes a silent, temporal threat: "The Ticker," a mysterious man in a gray suit. He is planting "Chaos-Knots" to disrupt their town's reality, and Lira is his target. She must use her wits to mend time itself before his Master Chronometer shatters their present forever.
