THE SCIENCE OF DISCWORLD

By Terry Pratchett

Synopsis

Through this original Terry Pratchett story (with intervening chapters from Jack Cohen and Ian Stewart) we discover how puny and insignificant individual lives are against a cosmic backdrop of creation and disaster. Yet, paradoxically, we see how the richness of a universe based on rules, has led to a complex world and at least one species that tried to get a grip of what was going on.

THE AMAZING MAURICE AND HIS EDUCATED RODENTS

Maurice, a streetwise tomcat, has the perfect money-making scam. Everyone knows the stories about rats and pipers, and Maurice has a stupid-looking kid with a pipe, and his very own plague of rats - strangely educated rats . . . But in Bad Blintz, the little con suddenly goes down the drain. For someone there is playing a different tune and now the rats must learn a new word. EVIL. It's not a game any more. It's a rat-eat-rat world. And that might only be the start . . .

A BLINK OF THE SCREEN

A collection of short stories and other short-form fiction from one of the world's best-loved authors. Here are characters both familiar and undiscovered; abandoned worlds and others still expanding; adventure, chickens, death, disco and, actually, some quite disturbing ideas about Christmas.

CARPE JUGULUM

Vampires have come to Lancre, but they're not what you'd expect. Sure, they drink blood and view humans as dinner, but they're modern and sophisticated. They've got style and fancy waistcoats. And they're not a bit afraid of garlic. The Magpyr family are out of the casket and want a bite of the future. But they haven't met the neighbours yet. Between them and Lancre stand a coven of four - Granny Weatherwax, Nanny Ogg, Magrat and young Agnes - and they don't take kindly to murderous intruders....Book twenty three in the series

THE CARPET PEOPLE

In the beginning, there was nothing but endless flatness. Then came the Carpet... That's the old story everyone knows and loves. But now the Carpet is home to many different tribes and peoples and there's a new story in the making. The story of Fray, sweeping a trail of destruction across the Carpet. The story of power-hungry mouls - and of two Munrung brothers, who set out on an amazing adventure. It's a story that will come to a terrible end - if someone doesn't do something about it.

THE COLOUR OF MAGIC

In the beginning there was...a turtle. 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. Particularly as it’s carried though space on the back of a giant turtle (sex unknown). It plays by different rules. But then, some things are the same everywhere. The Disc’s very existence is about to be threatened by a strange new blight: the world’s first tourist, upon whose survival rests the peace and prosperity of the land. Unfortunately, the person charged with maintaining that survival in the face of robbers, mercenaries and, well, Death, is a spectacularly inept wizard. This is the first book in the Discworld series.

DIGGERS

Book 2 of the Book of the Nomes: When humans threaten their new home in the quarry, the natural thing would be to run and hide. But the nomes have got the wild idea that they should fight back.

DRAGONS AT CRUMBLING CASTLE: AND OTHER STORIES

Fourteen fantastically funny stories from master storyteller Sir Terry Pratchett, full of time travel and tortoises, monsters and mayhem!

EQUAL RITES

Everybody knows there's no such thing as a female wizard. So when the wizard Drum Billet accidentally passes on his staff of power to an eighth daughter of an eighth son, a girl called Eskarina (Esk, for short), the misogynistic world of wizardry wants nothing to do with her. Thankfully Granny Weatherwax, the Discworld's most famous witch, has plenty of experience ignoring the status quo. With Granny's help, Esk sneaks her way into the magical Unseen University and befriends apprentice wizard Simon. But power is unpredictable, and these bright young students soon find themselves in a whole new dimension of trouble. Let the battle of the sexes begin....Book three in the series

ERIC

Ninth book of the Discworld series: Eric is the Discworld's only demonology hacker. The trouble is, he's not very good at it. All he wants is the usual three wishes: to be immortal, rule the world and have the most beautiful woman fall madly in love with him. But what he gets is Rincewind, the most incompetent wizard, and Rincewind's Luggage (the world's most dangerous travel accessory) into the bargain.

FEET OF CLAY

For Commander Vimes, Head of Ankh-Morpork City Watch, life consists of troubling times, linked together by...well, more troubling times. Right now, it's the latter. There's a werewolf with pre-lunar tension in the city, and a dwarf with attitude and a golem who's begun to think for itself, but that's just ordinary trouble. The real problem is more puzzling - people are being murdered, but there's no trace of anything alive having been at the crime scene. So Vimes not only has to find out whodunit, but howdunit too. He's not even sure what they dun. But soon as he knows what the questions are, he's going to want some answers. The Discworld novels can be read in any order but Feet of Clay is the third book in the City Watch series.

THE FIFTH ELEPHANT

They say that diplomacy is a gentle art. That mastering it is a lifetime's work. But you do need a certain inclination in that direction. It's not something you can just pick up on the job. 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. At some point during his ambassadorship, things went very wrong. It's snowing. It's freezing. And if Vimes can't make it through the forest, with only his wits and the gloomy trousers of Uncle Vanya (don't ask), there's going to be a terrible war. There are monsters on his trail. They're bright. They're fast. They're werewolves - and they're catching up. The Discworld novels can be read in any order but The Fifth Elephant is the fifth book in the City Watch series.

GOING POSTAL

Imprisoned in Ankh-Morpork con artist Moist von Lipwig is offered a choice: to be executed or to accept a job as the city's Postmaster General. It's a tough decision but he's already survived one hanging and isn't in the mood to try it again. The Post Office is down on its luck: beset by mountains of undelivered mail eccentric employees and a dangerous secret order. To save his skin Moist will need to restore the postal service to its former glory with the help of tough talking activist Adora Belle Dearheart. Who happens to be very attractive in an 'entire womanful of anger' kind of way. But there's new technology to compete against and an evil chairman who will stop at nothing to delay Ankh-Morpork's post for good...

GOOD OMENS

According to the Nice and Accurate Prophecies of Agnes Nutter - the world's only totally reliable guide to the future - the world will end on a Saturday. Next Saturday, in fact. Just after tea...

GUARDS! GUARDS!

'It was the usual Ankh-Morpork mob in times of crisis; half of them were here to complain, a quarter of them were here to watch the other half, and the remainder were here to rob, importune or sell hotdogs to the rest.' Insurrection is in the air in the city of Ankh-Morpork. The Haves and Have-Nots are about to fall out all over again. Captain Sam Vimes of the city's ramshackle Night Watch is used to this. It's enough to drive a man to drink. Well, to drink more. But this time, something is different - the Have-Nots have found the key to a dormant, lethal weapon that even they don't fully understand, and they're about to unleash a campaign of terror on the city. Time for Captain Vimes to sober up. The Discworld novels can be read in any order but Guards! Guards! is the first book in the City Watch series.

Tiffany Aching is ready to begin her apprenticeship in magic, but life isn't exactly what she thought it would be. She expects spells and magic - not chores and ill-tempered goats! Surely there must be more to witchcraft than this? And Tiffany will find that she needs her magic more than ever, to fight off the insidious, disembodied creature that is pursuing her. This time, neither Mistress Weatherwax (the greatest witch in the world) nor the fierce, six-inch-high Wee Free Men can protect her. In the end, it will take all of Tiffany's inner strength to save herself. A Hat Full of Sky is the second book in the Tiffany Aching series, but you can listen to the Discworld novels in any order.

HOGFATHER

Superstition makes things work in the Discworld and undermining it can have consequences. When Death realizes that belief in the Hogfather is dangerously low, he decides to take on the job. But it's just not right to find a seven-foot skeleton creeping down your chimney and trying to say 'ho, ho, ho'. It's the last night of the year, the time is turning, and if Susan, gothic governess and Death's granddaughter, doesn't sort everything out by morning, there won't be a morning.

But someone - or something - is inciting fear, generating dark thoughts and angry murmurs against witches. Tiffany must find the source of unrest and defeat the evil at its root. Aided by the tiny-but-tough Wee Free Men, Tiffany faces a dire challenge, for if she falls, the whole Chalk falls with her... I Shall Wear Midnight is the fourth book in the Tiffany Aching series, but you can listen to the Discworld novels in any order.

INTERESTING TIMES

The planet's oldest empire is 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: Rincewind, the world's dumbest wizard, Cohen the Barbarian, who stands 5 feet tall in his surgical sandals and a very special butterfly. This is book seventeen in the Discworld series.

JINGO

When the neighbours in question are the proud empires of Klatch and Ankh-Morpork, those are going to be some pretty large garden tools indeed. Of course, no-one would dream of starting a war without a perfectly good reason...such as a 'strategic' piece of old rock in the middle of nowhere. It is after all every citizen's right to bear arms to defend their own. Even if it isn't technically their own. And even if they don't have much in the way of actual weaponry. As two armies march, Commander Vimes of Ankh-Morpork City Watch faces unpleasant foes who are out to get him... and that's just the people on his side. The enemy might be even worse. The Discworld novels can be read in any order but Jingo is the fourth book in the City Watch series.

THE LAST CONTINENT

This is the Discworld's last continent, a completely separate creation. 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, all right? And it'll die in a few days, except.... Who is this hero striding across the red desert? Champion sheep shearer, horse rider, road warrior, beer drinker, bush ranger and someone who'll even eat a Meat Pie Floater when he's sober? A man in a hat whose luggage follows him on little legs, who's about to change history by preventing a swagman stealing a jumbuck by a billabong? Yes...all this place has between itself and wind-blown doom is Rincewind, the inept wizard who can't even spell wizard. Still...no worries, eh?

THE LAST HERO

Book 27 in the Discworld series. It's time the Last Hero in the world returns what the first hero stole. Trouble is, that'll mean the end of the world, if no one stops him in time.

THE LIGHT FANTASTIC

The Great A'Tuin, the heroic turtle who supports the weight of the entire Discworld, not to mention four giant elephants, swims through the galaxy day and night with the burden of being the only creature who knows exactly where the universe is going. Philosophers have long debated where this is, and are due to find out in about 2 months. Shall they worry? Well, they are on a collision course with a malevolent red star and only one person can save Discworld.

But now it's all gone wrong. Unless something drastic is done, there won't be time for anyone to invent spaceflight and the human race will be turned into ice-pops.

THE SCIENCE OF DISCWORLD IV: JUDGEMENT DAY

The fourth book in the Science of Discworld series, and this time around dealing with the really big questions, Terry Pratchett’s brilliant new Discworld story Judgement Day is annotated with very big footnotes (the interleaving chapters) by mathematician Ian Stewart and biologist Jack Cohen, to bring you a mind-mangling combination of fiction, cutting-edge science and philosophy.

A SLIP OF THE KEYBOARD

SMALL GODS

Religion is a competitive business in the Discworld. Everyone has their own opinion and their own gods, of every shape and size - all fighting for faith, followers, and a place at the top. So when the great god Om accidentally manifests himself as a lowly tortoise, stripped of all divine power, it's clear he's become less important than he realised. In such instances, you need an acolyte, and fast. Enter Brutha, the Chosen One - or at least the only One available. He wants peace, justice and love - but that's hard to achieve in a world where religion means power, and corruption reigns supreme....Book thirteen in the series

SNUFF

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. 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 out of his mind. But never out of guile.

SOURCERY

A 'sourcerer' is born in Discworld - a wizard so powerful that he makes all other magicians look like a bunch of fools in pointy hats.

THIEF OF TIME

'The universe is, instant by instant, recreated anew... The perfect moment is now. Be glad of it.' Time is a resource. Everyone knows it must be managed.

But the construction of the world's first truly accurate clock starts a race against, well... time. Monk Lu-Tze, his apprentice Lobsang Ludd and Death's granddaughter Susan must stop the clockmaker before he completes his task. Because a truly accurate clock will stop time completely. And then, there really will be no tomorrow...

THUD!

Koom Valley, the ancient battle where the trolls ambushed the dwarfs, or the dwarfs ambushed the trolls, was a long time ago.

And a witch has always protected Tiffany's land, to stop the nightmares getting through. Now the nightmares have taken her brother, and it's up to her to get him back. With a horde of unruly fairies at her disposal, Tiffany is not alone. And she is the twentieth granddaughter of her Granny Aching: shepherdess extraordinaire, and protector of the land. Tiffany Aching. Now there's a rather good name for a witch.

WINGS

Book 3 of the Book of the Nomes: Somewhere in a place so far up that there is no down, a ship is waiting to take the nomes home. And one nome, Masklin, knows that they've got to try and contact the ship. It means going to Florida (wherever that is), then getting to the launch of a communications satellite (whatever that is). A ridiculous plan. But Masklin doesn't know this, so he tries to do it anyway. And the first step is to try and hitch a ride on a new kind of truck, a truck with wings.

WINTERSMITH

The audiobook of Wintersmith is narrated by Indira Varma (Game of Thrones; Luther; This Way Up). BAFTA and Golden Globe award-winning actor Bill Nighy (Love Actually; Pirates of the Caribbean; Harry Potter and the Deathly Hallows) reads the footnotes, and Peter Serafinowicz (Star Wars: Episode I - The Phantom Menace; Shaun of the Dead) stars as the voice of Death. Steven Cree (Outlander; A Discovery of Witches) voices the Nac Mac Feegles. Featuring a new theme tune composed by James Hannigan. Saying it with frozen roses and icebergs Tiffany Aching leaps into a dance - and suddenly the spirit of winter is in love with her. He's showering her with snowflakes and offering her a crown of ice. Which is creepy, but also just a little bit... cool. Now she's dancing to his tune. She can't change the steps. But unless Tiffany can work out how to deal with the Wintersmith, there will never be another springtime...

WYRD SISTERS

Three witches gathered on a lonely heath. A king cruelly murdered, his throne usurped by his ambitious cousin. A child heir and the royal crown, both missing. Witches don't have these kinds of leadership problems themselves - in fact, they don't have leaders. Granny Weatherwax is the most highly regarded of the leaders they don't have. But even she finds that meddling in royal politics is a lot more complicated than certain playwrights would have you believe. Particularly when the blood on your hands just won't wash off....Book six in the series
