Hmmmm. The scientific and cultural analysis was really interesting, the woo-woo 'goddess array' stuff not so much. The 'therapist' who claimed to have had a vision of the virgin Mary while gazing into a woman's vagina was particularly cringey.
The last third was a little too heterocentric for my taste, but I still enjoyed the whole thing. Especially interesting connections to classic novels. Definitely worth the time!
Should be required reading for everyone with a yoni and for everyone that loves yonis.
