Just read an interview with Judy Hall from UK in The Mountain Astrologer Dec/Jan 2009. Her specialty is "Karmic Astrology".
Her work sounds fascinating and includes determining the karmic cause of illness, which has often led to healing and finding the karmic connections between people in relationships. She also works extensively with crystals.
You can go to her website and download many files on karmic astrology, crystal healing and other interesting subjects including her 119 page dissertation for her M.A. in Cultural Astronomy and Astrology. She has written many books including novels based on her own past lives (see the Amazon Carousel in the sidebar for some of her titles). If you are curious about her other titles, you can search in the Amazon Search box. She has many more books, but you can only put 10 on the Carousel.
I am fascinated by her work and plan to find out more about her. She does workshops on relationships and writing in the North of England. Maybe it's time for a trip! You can sign up for a reading online at her website.
