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.

The Great A'Tuin, the heroic turtle who supports the weight of the entire Discworld, not to mention four giant elephants, swims through the galaxy day and night with the burden of being the only creature who knows exactly where the universe is going. Philosophers have long debated where this is, and are due to find out in about 2 months. Shall they worry?

Right before the wise old wizard Drum Billet died, he passed on his magical staff of power to the newborn eighth son of an eighth son. Unfortunately, Drum Billet never bothered to check the gender of the newborn baby, and it turns out it was a girl. Now his chauvinistic colleagues are forced to deal with a young girl who has all the qualifications to join their all-male profession.

Mort, like many teenagers, is gangly, unpromising, and struggling with a menial job - in his case, as Death's apprentice. He can barely handle his simple task of ushering souls out of Discworld, but he really screws up when he meets the beautiful Princess Keli, who is scheduled to be assassinated.

A 'sourcerer' is born in Discworld - a wizard so powerful that he makes all other magicians look like a bunch of fools in pointy hats. Now, suddenly, Discworld is brought to the brink of an all-out thaumaturgical war. The only hope for peace is Rincewind, the failed magician who has a risky plan to save the world. He enlists the help of several odd new characters, including Conina the barbarian hairdresser, Nijel the Destroyer and a yuppie genie who sees lamps as a growth industry.

In Wyrd Sisters, the enchanting world of Discworld is turned upside down by three meddling witches: Granny Weatherwax, Nanny Ogg and Magrat Garlick. Their interference in royal politics causes kingdoms to wobble, crowns to topple, knives to flash and citizens to shudder in fear. Terry Pratchett's vividly imaginative story takes you on a journey with hunchbacked monarchs, lost crowns, disguised heirs, refuelling broomsticks and frightening thunderstorms, as the three sisters battle the odds to restore the rightful king to the throne.

It isn't easy, being a teenage pharaoh. You're not allowed to carry money, uninhibited young women peel your grapes for you, everyone thinks you're responsible for making the sun rise and the corn grow, you keep dreaming about seven thin cows and seven fat cows (one of them playing the trombone), and on top of everything else, the Great Pyramid has just exploded because of paracosmic instability.

If you find yourself ruminating on questions like "Where have all the dragons gone?" then this is the story for you. Explore the crazy, creepy land called Discworld, where you'll discover that the dragons aren't asleep or dead - they're dormant, packed in like huge, scaly sardines. Join in the search for the key to their closed-in, comatose world in this eighth fantastical Discworld novel.

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).

Cameras roll - which means the imps inside have to paint really fast - on the fantastic Discworld when the alchemists discover the magic of the silver screen. But what is the dark secret of Holy Wood hill? As the alien clichés of Tinsel Town pour into the world, it's up to the Disc's first film stars to find out.

In Terry Pratchett's Reaper Man, Death has left Discworld - but that's not necessarily a good thing. After all, chaos always ensues whenever important public services are withdrawn, and Discworld is no exception. Society is suddenly overrun by ghosts and poltergeists, while Dead Rights activist Reg Shoe finds himself busier than he's ever been and newly-deceased wizard Windle Poons rises from his coffin as a living corpse.

What could be easier than preventing a servant girl from marrying a prince, especially for three clever witches? But Granny Weatherwax, Nanny Ogg and Magrat Garlick face more than they bargained for when they journey to the distant city of Genua. For one thing, their power is limited to Mrs. Gogol's weak voodoo spells, a one-eyed cat and a secondhand magic wand that works only on pumpkins.

Brutha is the Chosen One. His god has spoken to him, admittedly while currently in the shape of a tortoise. Brutha is a simple lad. He can't read. He can't write. He's pretty good at growing melons. And his wants are few. He wants to overthrow a huge and corrupt church. He wants to prevent a horribly holy war.

On a hot midsummer night in Discworld, everything seems perfect - crop circles are turning up everywhere, the witch Magrat Garlick is getting married the next morning, and everyone's buzzing with excitement. Unfortunately, the Lancre All-Comers Morris Team has gotten drunk on a fairy mound, and the elves have returned with the traditional traits of the magical realm of Fairie: evil, malice, murder, cruelty, and kidnapping.

The town of Ankh-Morpork is in big trouble and the City Watch is desperate for a few good men to protect it. But all they've got are the dwarves Corporal Carrot and Lance-constable Cuddy, the troll Lance-constable Detritus, Lance-constable Angua, who is believed to be a woman and, worst of all, Corporal Nobbs, who has been disqualified from the human race for shoving! These underdogs need all the help they can get, for they've been given only 24 hours to clean up the war-torn town.

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.

Interesting Times, the 17th novel in Terry Pratchett's Discworld series, finds the planet's oldest empire in the midst of bitter turmoil after the publication of the revolutionary treatise What I Did on My Holidays. Workers, with nothing to lose but their water buffaloes, are joining forces against old warlords, spreading violence throughout Discworld's ancient cities. All that stands in the way of total destruction are three decidedly non-heroic creatures.

The show must go on, as murder, music and mayhem run riot in the night. The Opera House, Ankh-Morpork, is a huge, rambling building, where innocent young sopranos are lured to their destiny by a strangely familiar evil mastermind in a hideously deformed evening dress.

Who's murdering harmless old men? Who's poisoning the Patrician? As autumn fogs hold Ankh-Morpork in their grip, the City Watch has to track down a murderer who can't be seen. Maybe the golems know something - but the solemn men of clay, who work all day and night and are never any trouble to anyone, have started to commit suicide....

It's the night before Hogwatch. And it's too quiet. There's snow, there are robins, there are trees covered with decorations, but there's a notable lack of the fat man who delivers the toys....
