London, 1666. Fifteen-year-old Thomas Webb apprentices under Master Clockmaker John Fromanteel, learning the delicate art of timekeeping in a city on the brink of disaster. When the Great Fire consumes London, Thomas must rescue not just his master's priceless timepieces, but also secret designs for a revolutionary clock that could change navigation forever. Pursued by rival guilds and foreign spies who want the designs for themselves, Thomas discovers that keeping time is nothing compared to racing against it.
