I love reading what Grady Booch has to say. He’s an authority to me. In this book, he gives a lot of good advice. He gives a lot of good information what OO should be like, not just projects but advice on how to do better OO design. That’s good stuff. This book, however, shows its age. The good stuff is mixed with at times “dry” information, boring at times. A better format of the book would help as well. Nonetheless, a valuable book to read.
