Books on Astrology (Chinese and Western)

I'd like to hear some opinions from others about books they have read on Astrology both Chinese and Western. Lets see what you have found useful in your life, or maybe not so useful.

My own personal favorite is by Suzanne White. Chinese Astrology, Plain and Simple.

I found that it not only was helpful for my own personality, but also helpful in dealing with others who are different from myself. I also found that it was a very enjoyable read. I have referenced it often over the past couple of years. I believe that you will also enjoy reading it and re-reading it as I have.
So please feel free to let us all know what books you recommend or not. I'm sure there's more than me that's always open to find new reading material and learn new things.

Peace and Happy Reading!
