Making Money is one of the many stories in the Discworld universe. This particular story follows the character of Moist Lipwick, introduced in the previous story of Going Postal. In this story, Lipwick is given the task of improving and modernizing the mint of Ank Morpork. While this sounds really boring, the story is actually very funny and action packed.
Making Money is not my favorite Discworld book. It seems to me that Terry Pratchett is kind of in a rut with the way he writes his most recent stories. They are funny, but they follow a similar formula which gets a little boring after a while. It seems about every 10 or 15 years Pratchett develops a new formula for the Discworld books and sticks to that for a while. However, if you have never read any of his stories, then you should find them very fresh and enjoyable.
I personally enjoy the stories of Tiffany Aching in The Wee Free Men and sequels better than the normal Ank Morpork right now. It could be that I prefer satire on the human spirit more than satire on its money-making systems. At any rate, Making Money is very well written and challenged my vocabulary, which I appreciate in a book. Even though I found it slightly boring, I still give it four stars because of the exceptional writing quality.
