Sir Terry Pratchett's final Discworld novel, which features the witch Tiffany Aching.

The Colour of Magic, the first novel in Terry Pratchett's wildly imaginative Discworld series, takes the listener on a remarkable journey. The magical planet of Discworld is supported by four massive elephants who stand on the back of the Great A'Tuin, a giant turtle swimming slowly through the mysterious interstellar gulf. An eccentric expedition sets out to explore the planet, encountering dragons who only exist if you believe in them, and, of course, 'The Edge' of the planet.

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. And 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 occasionally snookered and out of his mind, but never out of guile. They say that in the end all sins are forgiven.

Tiffany Aching has spent years studying with senior witches, and now she is on her own. As the witch of the Chalk, she performs the bits of witchcraft that aren't sparkly, aren't fun, don't involve any kind of wand, and that people seldom ever hear about: She does the unglamorous work of caring for the needy. But someone - or something - is igniting fear, inculcating dark thoughts and angry murmurs against witches.

Football has come to the ancient city of Ankh-Morpork - not the old fashioned, grubby pushing and shoving, but the new, fast football with pointy hats for goalposts and balls that go gloing when you drop them. And now, the wizards of Unseen University must win a football match, without using magic, so they're in the mood for trying everything else.

At nine, Tiffany Aching defeated the cruel Queen of Fairyland. At 11, she banished an ancient body-stealing evil. At 13, Tiffany faces a new challenge: a boy. And boys can be a bit of a problem when you're 13. But the Wintersmith isn't exactly a boy. He is winter itself.

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.

Eleven-year-old Tiffany Aching wants to be a real witch. But a real witch doesn't casually step out of her body, leaving it empty. Tiffany does, and there's something just waiting for a handy body to take over. Something ancient and horrible, which can't die.

Young Susan has always suspected that her Grandfather was different, as though all the time he spent riding a white horse and wielding a scythe weren't enough of a giveaway. Now that her worst fears have been confirmed, Susan learns that she's expected to take over the family business when she grows up, even though most people mistake her for the Tooth Fairy. But as attractive as Death can be to many people, Susan is drawn into something else.

Up on the chalk downs they call The Wold, witches are banned - ever since the Baron's son vanished in the woods. Anyway, as all witches know, chalk's no good for magic. Nine-year-old Tiffany Aching thinks her Granny Aching - a wise shepherd - might have been a witch, but now Granny Aching is dead and it's up to Tiffany to work it all out when strange things begin happening.

You've heard of Faust - this is Eric. There's a difference. Eric is 14, lives on the famed and magical Discworld, and is the first ever demonology hacker. Fortunately, he doesn't succeed in raising any devils, but he does raise Rincewind (the most incompetent wizard in the universe) and the Luggage (the world's most dangerous travel accessory).

Rats! They're everywhere: in the breadbins, dancing across tabletops, stealing pies from under the cooks' noses. So what does every town need? A good piper to lure them away. That's where Maurice comes in. But he's only a cat (though one that talks).

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, alright?

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.

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.
