I suppose I will have to read The Illuminatus! Trilogy then at some time soon. I have life-changed quite a lot so one more time wouldn't harm I guess. Sounds intriguing!
As for Gwendolyn's little coven it is more about minimising the harm of the tree Gods and the sex-part is just the enfant sauvage, Gwendolyn, who tries to bend her little cult to her will, not with much success... that is until Phill, the chosen one, arrived :)
You should absolutely read this, it is one-of-a-kind and inspired many other books and writers. It has references to ... well, EVERYTHING, from native americans & lsd-in-lemonade, to the Cthulhu Mythos in Atlantis & resurrected nazis. And many philosophical concepts are presented, too. I'd like to hear your thoughts on it.
I can see that it is a MUST!
