Interesting Times by Terry Pratchett

In this book Rincewind gets sent across Discworld to the Counterweight Continent, where he quickly gets caught up in a revolution of sorts. He runs into Cohen the barbarian (also known as Ghengiz Cohen), who is determined to conquer, despite his old age and Teach, the member of his horde intent on civilizing the rest. I found this book humorous, but not as compelling as some of the other Discworld novels.
