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.

Finding himself alone on a desert island when everything and everyone he knows and loved has been washed away in a huge storm, Mau is the last surviving member of his nation. He's also completely alone - or so he thinks until he finds the ghost girl. She has no toes, wears strange lacy trousers like the grandfather bird and gives him a stick which can make fire. Daphne, sole survivor of the wreck of the Sweet Judy, almost immediately regrets trying to shoot the native boy.

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.

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.Marjorie Daw is a librarian, and takes her job – and indeed the truth of words – very seriously. She doesn’t know it, but her world and ours – Roundworld – is in big trouble.

The Western Front, 1916. Private Percy Blakeney wakes up. He is lying on fresh spring grass. He can hear birdsong, and the wind in the leaves in the trees.
