This is a small book which I bought because my daughter is a Sagittarius, however she is an indigo child and astrology, numerology, name analysis, and other metaphysical methods don't see to describe her accurately.
Nancy Ann Tappe was at a KRYON converence in Clearwater Beach several years ago and is mentioned in the book The Indigo Children: The New Kids Have Arrived by Lee Carroll and Jan Tober (ISBN 1-56170-608-6). She is also the author of Understanding Your Life Thru Color (ISBN 0-940399-00-8). She looked at my daughter's picture and said "Indigo conceptual," and she was right! I had suspected my college age daughter was special but wasn't sure about the indigo child label until Nancy Ann verified it.
This book on Sagittarius may fit a lot of other people, but not my special indigo daughter.
