To the thousands of tiny nomes who live under the floorboards of a large department store, there is no outside. Things like day and night, sun and rain are just daft old legends. Then a devastating piece of news shatters their existence: the Store, their whole world, is to be demolished.

The story is narrated by two very different teenagers, who each inhabit two extraordinarily different worlds. Arianrhod Hyde's world (or Roddy, as she prefers to be called) is very much the world of magic, pageantry and ritual. Not unlike Britain in King Arthur's Day, Roddy is daughter of two Court Wizards and therefore part of the King's Progress, travelling round the Islands of Blest and ready to take part in whatever ritual or ceremony is required, as it occurs.

Somewhere on the frontier between thought and reality exists the Discworld, a parallel time and place that 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.

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.

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.

Somewhere on the frontier between thought and reality exists the Discworld, a parallel time and place that might sound and smell very much like our own, but that looks completely different. It plays by different rules. Certainly it refuses to succumb to the quaint notion that universes are ruled by pure logic and the harmony of numbers. But just because the Disc is different doesn't mean that some things don't stay the same.

Once there was magic, and the magic lived in the dark forests. Until the warriors came... This is the story of a young boy wizard and a young girl warrior who have been taught since birth to hate each other like poison and the thrilling tale of what happens when their two worlds collide. Xar is a wizard boy who has no magic and will do anything to get it. Wish is a warrior girl, but she owns a banned magical object, and she will do anything to conceal it.

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?

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....

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.... 

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.

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.

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....

To the thousands of tiny nomes who live under the floorboards of a large department store, there is no Outside. Things like Day and Night, Sun and Rain are just daft old legends. Then a devastating piece of news shatters their existence: the Store, their whole world, is to be demolished. And it's up to Masklin, one of the last nomes to come into the Store, to mastermind an unbelievable escape plan that will take all the nomes into the dangers of the great Outside.
