Book excerpt: In this breakthrough book, Stephen Arroyo discusses the two subjects that people most often want to understand through astrology: Relationship Compatibility and the Cycles that Shape Our Lives. The spontaneous quality of this book makes it especially informative and valuable, since it includes numerous insights and observations not found in more conventional presentations. As many reviewers have observed, the sections on precisely how to compare charts to analyze relationships and how to use the houses in such comparisons are completely unique and original contributions to the field of astrological psychology.
