The Colour of Magic

On a world supported on the back of a giant turtle (sex unknown), a gleeful, explosive, wickedly eccentric expedition sets out. There's an avaricious but inept wizard, a naive tourist whose luggage moves on hundreds of dear little legs, dragons who only exist if you believe in them, and of course THE EDGE of the planet...

The wackiest and most original fantasy since Hitchhikers Guide to the Galaxy.
