Without a doubt this is the most complete and well-researched book on Transpluto (Planet X) ever written. Valerie Vaughan presents her case for the existence of Planet X and goes further by offering an interpretation of its astrological influence and meaning. She argues that Transpluto should be named Persephone because its influence is feminine. She begins the book with descriptions of the circumstances of the discoveries of Uranus, Neptune, Pluto, and Chiron, all named for male deities and all symbolizing masculine functions. Included also is a 112-year ephemeris for Persephone/Transpluto.
