Audiobook Title:
The Carpet People
By: Terry Pratchett

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 the story of two Munrung brothers, who set out on an adventure to end all adventures when their village is flattened. 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.
