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.

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....

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.

To the consternation of the patrician, Lord Vetinari, a new invention has arrived in Ankh-Morpork - a great clanging monster of a machine that harnesses the power of all of the elements: earth, air, fire and water. This being Ankh-Morpork, it’s soon drawing astonished crowds, some of whom caught the zeitgeist early and arrive armed with notepads and very sensible rainwear.

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'.

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.

The town of Ankh-Morpork is in big trouble and the City Watch is desperate for a few good men to protect it. But all they've got are the dwarves Corporal Carrot and Lance-constable Cuddy, the troll Lance-constable Detritus, Lance-constable Angua, who is believed to be a woman and, worst of all, Corporal Nobbs, who has been disqualified from the human race for shoving! These underdogs need all the help they can get, for they've been given only 24 hours to clean up the war-torn town.

Commander Sam Vimes of the Ankh-Morpork City Watch will be damned if he lets anyone disturb his city's always tentative peace, and that includes a rabble-rousing dwarf from the sticks who's been stirring up trouble on the eve of the anniversary of one of Discworld's most infamous historical events.

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.

If you find yourself ruminating on questions like "Where have all the dragons gone?" then this is the story for you. Explore the crazy, creepy land called Discworld, where you'll discover that the dragons aren't asleep or dead - they're dormant, packed in like huge, scaly sardines. Join in the search for the key to their closed-in, comatose world in this eighth fantastical Discworld novel.

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.

Eleven-year-old Tiffany Aching wants to be a real witch. But a real witch doesn't casually step out of her body, leaving it empty. Tiffany does, and there's something just waiting for a handy body to take over. Something ancient and horrible, which can't die.

Tiffany Aching has spent years studying with senior witches, and now she is on her own. As the witch of the Chalk, she performs the bits of witchcraft that aren't sparkly, aren't fun, don't involve any kind of wand, and that people seldom ever hear about: She does the unglamorous work of caring for the needy. But someone - or something - is igniting fear, inculcating dark thoughts and angry murmurs against witches.
