Ms. Teal has already written a comprehensive overview of what her book does. What I love about this work is the information about Mercury, Venus, Mars, and Jupiter Returns, because there is so little else written on them. She covers a lot of information including progressions, transits, and other Returns as well. There are numerous examples to illustrate in a well-organized, very readable work that is easy to reference. Lots of valuable information not readily available elsewhere!
In her second book Celeste Teal reveals something more about techniques for prediction. Though she refers a lot to techniques already mentioned in her first book the most valuable parts in this book are about the return charts and the transit descriptions by dr. Smith. This book is a must read for all astrologers.
