This book takes you from knowing nothing about Feng Shui to understanding the breadth of the subject. It covers a number of theories, which I found very interesting, but confusing. A number of the theories seem to conflict with each other, and it became difficult to work out how you could apply them to yourself. This is especially true when you're sharing a home, and your signs are in conflict with your partner.
If you're interested in Feng Shui and are thinking about moving house, this would be a good book to tell you what to look for.
Later chapters concentrate on different areas of your life, eg career, relationships, and give advice on how you can enhance those areas. This is the part I was interested in on buying the book, and found it didn't tell me enough.
A good book as part of a set, and a good starting point.
