This book is not about feng shui. It is simply about decluttering your household (and your body, for those of you who are prepared to read about colon cleansing) from the perspective of a feng shui practitioner. If you want a book about feng shui, get something else.
I am always highly suspicious of any book that gets "This changed my life" reviews. I find the more people write glowing categorical reviews of that nature, the more others feel the need to slam what's being reviewed and call it useless. When you open a book expecting miracles, you'll get disappointed.
That being said:
Personally, I couldn't put this book down. I hadn't planned to buy something like this (I generally avoid self-help books), but when I thumbed through it in the bookstore I was hooked. I kept finding myself and my situation in what she was writing about. Having finished it, I've started to tackle some of the clutter that's sat around my apartment for months.
The author walks her talk, and is quite readable. There were a couple of grammatical issues I thought a good proofreader would catch ("disorientating" in the place of "disorienting", for example), and I do feel that the chapter on bodily health insisted too much on fasting and colon cleansing for the context of the book, and should have been seriously pared down or cut entirely. This book addresses homes, and the health of the body is a subject requiring several books of its own. But if you're feeling depressed by the clutter in your life, and your problem is not so much time as motivation to make a change, this book could be very useful for you.
I know I'm keeping my copy.
