Twoflower was a tourist, the first ever seen on the Discworld. Tourist, Rincewind decided, meant idiot. Somewhere on the frontier between thought and reality exists the Discworld, a parallel time and place which might sound and smell very much like our own, but which looks completely different.

Time is a resource. Everyone knows it has to be managed. And on the Discworld that is the job of the Monks of History. 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 only be the start of everyone's problems.

Sir Terry Pratchett's final Discworld novel, which features the witch Tiffany Aching.

A few days ago Sam Vimes was a copper. An important copper, true - chief of police - but still, at his core, a policeman. But today he is an ambassador - to the mysterious, fat-rich country of Uberwald. Today, Sam Vimes is also a man on the run. He has nothing but his native wit and the gloomy trousers of Uncle Vanya. It's snowing. It's freezing. And if he can't make it through the forest to civilization there's going to be a terrible war. There are...

Someone is murdering old men, the Patrician has been poisoned, the clay workers have started committing suicide, and there is a werewolf suffering from pre-lunar tension.

Football has come to the ancient city of Ankh-Morpork - not the old fashioned, grubby pushing and shoving, but the new, fast football with pointy hats for goalposts and balls that go gloing when you drop them. And now, the wizards of Unseen University must win a football match, without using magic.

Discworld's last continent, a completely separate creation, is a hot, dry place where everything is poisonous. All that stands betwen this place and wind-blown doom is Rincewind, an inept wizard who is the only hero left.

It's an offer you can't refuse. Who would not wish to be the man in charge of Ankh-Morpok's Royal Mint and the bank next door? It's a job for life, but, as former con-man Moist von Lipwig is learning, the life is not necessarily for long.

The oldest and most inscrutable empire in the Discworld is in turmoil, brought about by the revolutionary treatise 'What I Did On My Holidays'. Workers are uniting, with nothing to lose but their water buffaloes. Warlords are struggling for power. War (and Clancy) are spreading throughout the ancient cities.

It's a hot midsummer night. The crop circles are turning up everywhere, and Magrat the witch is going to be married in the morning - everything ought to be going like a dream. Unfortunately, things aren't about to run smoothly.
