Terry Pratchett

In the 'fantasy' universe of the phenomenally bestselling Discworld series, everything runs on magic and common sense. The world is flat and million-to-one chances happen nine times out of ten. Our world seems different - it runs on rules, often rather strange ones. Science is our way of finding out what those rules are. The appeal of Discworld is that it mostly makes sense, in a way that particle physics does not.

The acclaimed Science of Discworld centred on an original Pratchett story about the Wizards of Discworld. In it they accidentally witnessed the creation and evolution of our universe, a plot which was interleaved with a Cohen & Stewart non-fiction narrative about Big Science. In The Science of Discworld II our authors join forces again to see just what happens when the wizards meddle with history in a battle against the elves for the future of humanity on Earth. London is replaced by a dozy Neanderthal village.

Roundworld is in trouble again, and this time it looks fatal. Having created it in the first place, the wizards of Unseen University feel vaguely responsible for its safety. They know the creatures who lived there escaped the impending Big Freeze by inventing the space elevator - they even intervened to rid the planet of a plague of elves, who attempted to divert humanity onto a different time track. But now it's all gone wrong - Victorian England has stagnated and the pace of progress would embarrass a limping snail.

With a foreword by Neil Gaiman Terry Pratchett has earned a place in the hearts of readers the world over with his bestselling Discworld series – but in recent years he has become equally well-known and respected as an outspoken campaigner for causes including Alzheimer’s research and animal rights.

In the four decades since his first book appeared in print, Terry Pratchett has become one of the world’s best-selling and best-loved authors. Here for the first time are his short stories and other short form fiction collected into one volume. A Blink of the Screen charts the course of Pratchett’s long writing career: from his schooldays through to his first writing job on the Bucks Free Press, and the origins of his debut novel, The Carpet People; and on again to the dizzy mastery of the Discworld series.

Not many people can see the dead (and not many would want to). Twelve-year-old Johnny Maxwell can. And he's got bad news for them: the members of the council want to sell the cemetery as a building site. But the dead aren't going to take it lying down - especially since it's Halloween tomorrow. Besides, they're beginning to find that life is a lot more fun than it was when they were...well...alive. Particularly if they break a few rules.

Johnny Maxwell and his friends have to do something when they find Mrs Tachyon, the local bag lady, semi-conscious in an alley...as long as it's not the kiss of life. But there's more to Mrs Tachyon than a squeaky trolley and a bunch of dubious black bags. Somehow she holds the key to different times, different ears: including the Blackbury Blitz in 1941. Suddenly, now isn't the safe place Johnny once thought it was as he finds himself caught up more and more with then.

As the mighty alien fleet from the very latest computer game thunders across the computer screen, Johnny prepares to blow them into the usual million pieces. And they send him a message: We surrender. They're not supposed to do that! They're supposed to die. And computer joysticks don't have 'Don't Fire' buttons. But it's only a game... isn't it?

In the beginning, there was nothing but endless flatness. Then came the Carpet.... That's the old story everyone knows and loves (even if they don't really believe it). 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 adventure to end all adventures when their village is flattened.

From Snuff: Vimes looked at the cover. The title was The World of Poo. When his wife was out of eyeshot he carefully leafed through it. Well, okay, you had to accept that the world had moved on and these days’ fairy stories were probably not going to be about twinkly little things with wings. As he turned page after page, it dawned on him that whomever had written this book, they certainly knew what would make kids like Young Sam laugh until they were nearly sick. The bit about sailing down the river almost made him smile.
