All combinations of aspects are covered with interesting examples drawn from the author's own experience. Widely regarded as one of the best astrology books available.

A yod is formed when two planets that are in sextile also form inconjuncts to another planet. Karen has been studying yods for many years, and this book is the definitive work on the subject. Also included here is a discussion of how the energies of unaspected planets, and planets in duet (that only aspect each other) are expressed in a person's birth-chart. The book includes case histories of famous people (Clinton and Lewinsky, Charles and Diana etc.) plus those of Karen's own clients.
