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.

The world will end on Saturday. Next Saturday. Just before dinner, according to The Nice and Accurate Prophecies of Agnes Nutter, Witch, the world's only completely accurate book of prophecies, written in 1655. The armies of Good and Evil are amassing, and everything appears to be going according to Divine Plan. Except that a somewhat fussy angel and a fast-living demon are not actually looking forward to the coming Rapture. And someone seems to have misplaced the Antichrist.

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.

In the beginning, there was nothing but endless flatness. Then came the Carpet.... That's the old story everyone knows and loves (even if they don't really believe it).

The story of power-hungry mouls - and of two Munrung brothers, who set out on an adventure to end all adventures when their village is flattened.
