This book has 13 lessons : secondary progressions, the progressed moon, planets changing directions, solar arc directions, progressions and directions, the changing ascendant and sun, transits, transits in actions, lunations and eclipses, cycles, solar returns, lunar return, putting it all together.
I found very useful and accurate the indicators for marriage, children and pregnacy, profession, job change, home change, death, divorce, health for the delienation of solar returns. I have never found anywhere else a lot of useful rules and details for the solar returns.
Marion D. March&Joan McEvers share their experiences after years of reading charts with the readers, valuable informations with detailed descriptions, rules for interpretations, explaining notes and examples. It's a mix of theory and practice for different forecasting techniques.
I have already read 5 volumes of these authors' collection. I highly reccomend all their books.
