Great follow up to Going Postal, but not as enjoyable as the first one. In this one, the reformed thief/con man/scammer Moist Von Lipwig is put in charge of the Ankh-Morpork Bank.
It is an outrageous and sarcastic commentary on the financial systems and the very meaning of money in our own world. I have grown to love the character of Von Lipwig and the whole world of Discworld.
This instalment is one of the more "mature" ones in terms of content and themes. But it pulls off a stinging critique of our obsession with money and the power it conveys.
