If you want to learn evolutionary astrology, are there any books to read besides Inner Sky?

There are no other books on evolutionary astrology, but you can read Jeff Green's Pluto: A Journey of Soul Evolution and Pluto: Soul Evolution in Intimate Relationships. The author Jeff Green, like Stephen forest, is one of the founders of evolutionary astrology. Although these two books are about evolutionary astrology, they are also in line with the idea of evolution.
