Another story centering on Moist von Lipwig (from Going Postal). In this one he is required to sort out the mint and central bank. The characters are fun, but overall the story lacks the bite of Pratchett's best recent novels (I'm thinking of Going Postal and Thud!, in particular). It feels like the ideas didn't quite come together as they were intended to, or something.
Still, there is plenty to enjoy along the way.
