"Philosophical humor of the highest order." -Kirkus Reviews Time is at an end for the Discworld unless a trio of unusual allies can save it in New York Times bestselling author Terry Pratchett's "funny, charming" (Chicago Tribune) tale. "The universe is, instant by instant, recreated anew . The perfect moment is now. Be glad of it." Time is a resource that must be managed. It can be allowed to move quickly or slowly, but it must never stop. In the Discworld, only the venerable Monks of History are entrusted with overseeing time, to ensure that tomorrow always comes.

But a young horologist is about to start a race against time. He's constructing the world's first truly accurate clock, and if this Perfect Clock starts ticking, it will stop time completely. It's up to Monk Lu-Tze, his apprentice Lobsang Ludd, and Death's granddaughter Susan to stop him, or there really will be no tomorrow. The Discworld novels can be read in any order but Thief of Time is the fifth and final book in the Death series. The full collection includes: Mort The Reaper Man Soul Music Hogfather Thief of Time.
