AstroBookReview: What Does Joan Say?
While Joan does not go into every single tedious detail, nor does she share in great detail too many horoscopes (she talks about aspects of "Ronnie" and Gorbachev the most, Nancy forbid her from sharing details of hers), she does talk a good deal about how she constantly was working on charts to diminish/eliminate bad events and maximize the good ones. She claims to have a super-tedious way of doing so, though she doesn't share it. (With good reason, it does sound hard.) Though even she admits that towards the end, the stars were just plain unfriendly to Reagan and she couldn't do much about it. But it certainly does explain the "Teflon"-ness of the presidency and how she avoided assassination. The sheer amount of work is amazing.
She does give a useful primer at the back of the book on astrology for noobs as well.
If you can get ahold of this book, it's a good read for astrologer-types.
