When quiet clockmaker Arden Vale repairs an old brass clock in his shop, it begins doing something impossible it stops at midnight and reveals a hidden thirteenth hour that does not belong to ordinary time. When the strange hour appears, a secret doorway opens inside the shop, leading to a forgotten corridor where time itself has been broken. Inside waits a man who was trapped there thirty years ago during a dangerous experiment with time. Now that the clock has been repaired, the hour has returned—and the man is trying to escape. As reality begins to fracture and the thirteenth hour collapses around them, Arden discovers that fixing the clock made him the anchor of the hour, the only person who can decide how the moment ends. But closing the hour means someone must remain trapped inside it forever. A suspenseful time-bending mystery about forgotten moments, dangerous inventions, and the cost of repairing time itself.
