Thomas J. Clare

The Opera House in Ankh-Morpork is home to music, theatrics and a harmless masked Ghost who lurks behind the scenes. But now a set of mysterious backstage murders may just stop the show. Agnes Nitt has left her rural home of Lancre in the hopes of launching a successful singing career in the big city. The only problem is, she doesn't quite look the part. And there are two witches who would much rather she return home to join their coven.

Time is a resource. Everyone knows it has to be managed. You mess with it at your peril. You can let it move fast or slowly, but what you mustn't do is allow it to stop. The Monks of History have the glamorous job of time management in the Discworld. They store it and pump it from the places where it's wasted (like underwater—how much time does a codfish need?) to places like cities, where there's never enough time. 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.
