This book covers the female life cycle and has a section corresponding for every seven years. Each 7 year chapter goes over the theme that normally goes through such as the physical/ hormonal changes, the psychological challenges, drives and relationships. Not much was new for me at this point as I've quite familiar with a woman's 'blood mysteries'. But for a younger opened minded women, this would be very insightful and helpful with information about future stages all girls/women go through. Easy to read and understand. My favorite part was when she talked about mitochondria DNA and how unique and powerful a woman's is, and the special way it moves through generations, only via the Mother's Line. She notes that the sperm does contain (limited) MT DNA, but it is there only to propel the sperm forward and once it reaches an egg, the egg absorbs the nucleus and discards the rest including the male/sperm mitochondria, so only the female/woman can pass on that particular DNA.
