In the beginning, there was nothing but endless flatness. Then came the Carpet . . .

That's the old story everyone knows and loves. But now the Carpet is home to many different tribes and peoples and there's a new story in the making. The story of Fray, sweeping a trail of destruction across the Carpet. The story of power-hungry mouls - and of two Munrung brothers, who set out on an amazing adventure.

It's a story that will come to a terrible end - if someone doesn't do something about it. If everyone doesn't do something about it . . .

Co-written by Terry Pratchett, aged seventeen, and master storyteller, Terry Pratchett, aged forty-three.
