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.

Most of us grow up having always known to touch wood or cross our fingers, and what happens when a princess kisses a frog or a boy pulls a sword from a stone, yet sadly, some of these things are now beginning to be forgotten. Legends, myths, and fairy tales: our world is made up of the stories we told ourselves about where we came from and how we got there. It is the same on Discworld, except that beings which on Earth are creatures of the imagination - like vampires, trolls, witches, and possibly, gods - are real, alive and in some cases kicking on the Disc.

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.

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.

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.

Sell the cemetery? Over their dead bodies.... 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 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.

It can take you to the top of the highest mountain or down to the bottom of the deepest depths of the sea. This where it took Doggins on his 'Awfully Big Adventure': a quest full of magic and flying machines. (And the world’s best joke - trust me, it’s hilarious.) It took three young inventors to the moon (where they may or may not have left a bottle of lemonade) and a caveman on a trip to the dentist. You can join them on these adventures, and many more, in this incredible collection of stories.... 

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.

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?

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. Where have the mud, blood, and blasted landscape of No Man's Land gone? Madison, Wisconsin, 2015. Cop Monica Jansson is exploring the burned-out home of a reclusive - some said mad, others dangerous - scientist when she finds a curious gadget: a box containing some wiring, a three-way switch and a potato. It is the prototype of a life-changing invention....

Somewhere in a place so far up that there is no down, a ship is waiting to take the nomes home, back to wherever they came from. And one nome, Masklin, knows that they've got to try and contact the ship.

Poor Mr. Swimble is having a bad day. Rabbits are bouncing out of his hat, pigeons are flying out of his jacket and every time he points his finger, something magically appears - cheese sandwiches, socks...even a small yellow elephant on wheels! It's becoming a real nuisance - and he's allergic to rabbits. His friends at the Magic Rectangle can't help, but the mysterious vacuum cleaner he saw that morning may have something to do with it....

The stockings are hanging ready, the sherry and pies are waiting by the fireplace - but where is the jolly fat man with his sack? It's not right to find Death creeping down chimneys and trying to say 'Ho ho ho' - but someone's got to bring the little kiddies their presents. Or else they might stop believing. Belief is important in Discworld, particularly on the last night of the year when the time is turning. If the real man in the red suit isn't found by morning, there won't be a morning. Ever again.... 

Dragons have invaded Crumbling Castle, and all of King Arthur’s knights are either on holiday or visiting their grannies. It’s a disaster! Luckily, there’s a spare suit of armour and a very small boy called Ralph who’s willing to fill it. Together with Fortnight the Friday knight and Fossfiddle the wizard, Ralph sets out to defeat the fearsome fire-breathers. But there's a teeny weeny surprise in store.

A bright new dawn is just around the corner for thousands of tiny nomes when they move into the ruined buildings of an abandoned quarry. Or is it?
