Query: Very superficial book about business rules

Parts of this book seem to me superficial. It explains only very basic concepts about business rules and it does not go into detail how you can manage and implement these rules in a company. The book has only 99 pages whereby 30% of the book are cartoons and pictures. Therefore, I think that the book is totally overpriced and doesn't deliver enough knowledge how to apply business rules in a real-world situation.
