Women have always known that we are cyclical creatures, strongly influenced by our daily, monthly, and yearly rhythms. Finally, we have a book that examines these natural cycles as gifts rather than weaknesses or curses. Dividing the female life span by the mystical number of seven years, Joan Borysenko reveals the biological forces that drive our physical, emotional, and spiritual development. This is a pragmatic book filled with groundbreaking medical research; it is also a book that dares to explore the link between female biology and female mystery.
