Even though I have been studying astrology for 30 years now, I still refer to this book. It is a treasure in my library! I had an original copy but gave it away (always happens) and have now purchased a couple more copies for the next time I give one away (that way I’ll still have my own copy). When there has been only one book that I had to choose to bring to the attention of one that wanted like to deepen their knowledge of astrology, this book has been it. Steven Forrest is brilliant!
