Not strictly speaking a book about Martial Arts but a very good read on a sort of Shaolin/You don`t even know Kung fu/Be scared of the little quiet Chinese guy level. Like all Pratchett books there`s a little somehting under the surface.
I liked the part where he was asked if he was any good fighting and he said technically no (with the in unsaid "I'm really good")
Heh, funny to see one of Pratchetts books appear in a martial arts forum. I'm a fan too. I especially loved the No Kando style and Oki Doki.
