Time is a resource. Everyone knows it has to be managed. And on the Discworld that is the job of the Monks of History, who store it and pump it from places where it 's wasted (like under water - how much time does a codfish need?) to places like cities, where there's never enough of it. But the construction of the world's first truly accurate clock starts a race against, well, time for Lu Tze and his apprentice Lobsang Ludd. Because it will stop time. And that will be only the start of everyone's problems. Thief of Time comes with a full supporting cast of heroes and villians, yetis, martial artists and Ronnie, the fifth horseman of the Apocalypse (who left before they were famous).
