Astrological Gifts, Challenges, and Returns The Little Book of Saturn, a smart, friendly introduction to the astrological Saturn, is a book for curious readers who know there is more to astrology than their sun signs. Saturn has traditionally been considered the planet of challenges, but the life lessons that this stern planet brings are necessary for personal growth. This book is suitable for beginners and experts alike. It discusses the influence of Saturn on the natal horoscope, focusing on Saturn in its various places in the birth chart and exploring the various transits, especially the return(s), which brings with it a period of transition that is often feared, but Aliza Einhorn shows you how to understand and navigate them with confidence.
