Rincewind saves my Discworld every time. He is just priceless. Our satire this time--the Art of War. The gods are bored and decide to play a game.
Fate is playing Imperial China on the verge of the communist revolution. The Lady decides to counter with the one pawn Fate will never be able to anticipate, the Great Wizzard Rincewind. The other pawns on the board are Genghiz Cohen, the barbarian invader from the north; Hex, the super conglomeration made by the Unseen wizards; Lord Hong, the dreamer of empires; the Luggage, and little luggage babies (cute!); and the return of the amazing Twoflower, tourist extraordinaire.
Worlds collide as Cohen tries to civilize up in order to steal the empire, Lord Hong attempts a coup, and Rincewind is magically transported with Unseen University's version of physics. The amount of fumbling in this novel absolutely restored the humor I had been missing in the last couple novels.
What excited me the most, however, was the ending. Instead of being transported back to Ankh-Morpork, Rincewind clearly lands in a Discworld version of the Australian outback. Which means more novels about Rincewind! Luck clearly has a great affinity for Rincewind, though I'm sure he doesn't see it that way.
May you live in interesting times.
