Marion and Joan, proven extraordinarily successful over a quarter-century, update and refine their monument to our learning: with gentle, memorable sentences about all the basics of astrology, with tests for each lesson keeping us productive and rewarded on every page, they charm us to look into new windows, to discover with real know-how the individual life shown in every horoscope. . . . The easiest-to-understand orientation to astrology that exists today. - Noel Tyl, astrologer and author.
