|Thief Of Time Corgi Audio Books 2001 ISBN 0-552-14841-5
Time is a resource. Everyone knows it has to be managed. And on Discworld that is the job of the Monks of History, who store it and pump it from the places where its wasted (like underwater-how much time does a codfish need?) to places like cities, where theres never enough time.
But the construction of the worlds 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 everyones problems.
Thief of Time comes complete with a full supporting cast of heroes and villains, yetis, martial artists and Ronnie, the fifth horseman of the Apocalypse (who before they became famous).
