pocket-sized book of many of the published Rules of Acquisition with a cute forward by Quark. Only 3 stars though, because it doesn't have all the Rules which have been publishes actually in this book. All the published rules can be found in "Legends of the Ferengi" ISBN 9780671007287. I don't know why this book, written by the same author, would leave any of them out.
It should be noted - not all 285 Rules of Acquisition were actually ever published.
