Imagine a million clever rats. Rats that dont run. Rats that fight...Maurice, a scruffy tomcat with an eye for the main chance, has the perfect fiddle going. He has a stupid-looking kid for a piper, and he has his very own plague of rats - rats who are strangely educated, so Maurice can no longer think of them as lunch. And everyone knows the stories about rats and pipers - and is giving him lots of money...Until they try the trick in the far-flung town of Bad Blintz, and the nice little con suddenly goes down the drain. Someone there is playing a different tune. A dark, shadowy tune. Something very, very bad is waiting in the cellars. The rats must learn a new word. Evil. Its not a game any more. Its definitely a rat-eat-rat world down there. In fact, that might only be the start...Bestselling novelist Terry Pratchett leads readers from tale to tail in a darkly imaginative and fiendishly entertaining story, the first for younger readers set in the Discworld universe, the setting of his phenomenally successful fantasy novels.
