Koom Valley? That was where the trolls ambushed the dwarfs, or the dwarfs ambushed the trolls. It was far away. It was a long time ago. But if he doesn't solve the murder of just one dwarf, Commander Sam Vimes of Ankh-Morpork City Watch is going to see it fought again, right outside his office.

Truth! Justice! Freedom! And a hard-boiled egg! Commander Sam Vimes of the Ankh-Morpork City Watch had it all. But now he's back in his own rough, tough past, without even the clothes he was standing up in when the lightning struck. Living in the past is hard. Dying in the past is incredibly easy. But he must survive; he has a job to do.

A weathercock has risen from the sea of Discworld and suddenly you can tell which way the wind is blowing. A new land has surfaced and so have old feuds. And as two armies march, Commander Vimes of Ankh-Morpork City Watch has got just a few hours to deal with a crime so big that there's no law against it. It's called 'war'.

Sam Vines is a man on the run. Yesterday, he was a duke, a chief of police, and an ambassador. Now he has nothing but his native wit and the gloomy trousers of Uncle Vanya. And if he can't make it through the forest to civilisation, there's going to be a terrible war. But there are monsters on his trail. They're werewolves - and they're catching up. Sam Vimes is out of time and already out of breath....

William de Worde, the accidental editor of Discworld's first newspaper, just wants to get to the truth. Unfortunately, everyone else wants to get at William. And it's only the third edition. Browse more novels of Discworld.

It's an offer you can't refuse. Who would not wish to be the man in charge of Ankh-Morpork'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 Chief Cashier is almost certainly a vampire. There's something nameless in the cellar (and the cellar itself is pretty nameless), and it turns out that the Royal Mintruns at a loss.

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 the places where it's wasted (like the 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.

It is a truth universally acknowledged that a policeman taking a holiday would barely have had time to open his suitcase before he finds his first corpse. And Commander Sam Vimes of the Ankh-Morpork City Watch is on holiday in the pleasant and innocent countryside, but not for him a mere body in the wardrobe. There are many, many bodies and an ancient crime more terrible than murder. He is out of his jurisdiction, out of his depth, out of bacon sandwiches and occasionally snookered and out of his mind, but never out of guile. They say that in the end all sins are forgiven.

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, so they're in the mood for trying everything else.

Who's murdering harmless old men? Who's poisoning the Patrician? As autumn fogs hold Ankh-Morpork in their grip, the City Watch has to track down a murderer who can't be seen. Maybe the golems know something - but the solemn men of clay, who work all day and night and are never any trouble to anyone, have started to commit suicide....

It's the night before Hogwatch. And it's too quiet. There's snow, there are robins, there are trees covered with decorations, but there's a notable lack of the fat man who delivers the toys....

It's hot. It's dry...very dry. There was this thing once called The Wet, which no one believes in. Practically everything that's not poisonous is venomous. But it's the best bloody place in the world, alright?

Interesting Times, the 17th novel in Terry Pratchett's Discworld series, finds the planet's oldest empire in the midst of bitter turmoil after the publication of the revolutionary treatise What I Did on My Holidays. Workers, with nothing to lose but their water buffaloes, are joining forces against old warlords, spreading violence throughout Discworld's ancient cities. All that stands in the way of total destruction are three decidedly non-heroic creatures.

Up on the chalk downs they call The Wold, witches are banned - ever since the Baron's son vanished in the woods. Anyway, as all witches know, chalk's no good for magic. Nine-year-old Tiffany Aching thinks her Granny Aching - a wise shepherd - might have been a witch, but now Granny Aching is dead and it's up to Tiffany to work it all out when strange things begin happening.

Suddenly, condemned arch-swindler Moist von Lipwig found himself with a noose around his neck and dropping through a trapdoor into...a government job? By all rights, Moist should be meeting his maker rather than being offered a position as postmaster by Lord Vetinari, supreme ruler of Ankh-Morpork.
