The Colour of Magic

The first novel of the Discworld series. On a world supported on the back of a giant turtle, a wickedly eccentric expedition sets out. There’s Rincewind, an avaricious but inept wizard, Twoflower, a naive tourist whose murderous luggage moves on hundreds of little legs, dragons who only exist if you believe in them, and of course, the Edge of the Discworld, and its circumference. . .
