Imagine a flat world, sitting on the backs of four elephants, who hurtle through space balanced on a giant turtle. The Discworld is a place (and a time) parallel to our own - but also very different. That is the setting for Terry Pratchett's phenomenally successful Discworld series, which now celebrates its 25th anniversary.

The Discworld Graphic Novels presents the very first two volumes of this much-loved series in graphic novel form. First published fifteen years ago, these fully illustrated versions are now issued for the first time in hardback. Introduced here are the bizarre misadventures of Twoflower, the Discworld's first ever tourist, and possibly - portentously - its last, and his guide Rincewind, the spectacularly inept wizard.Not to mention the Luggage, which has a mind of its own.
