William did not tell his daughter Eowyn the entire truth about the First Commune. He was embarrassed about many of the things he and her mother Jane did. More importantly, he felt so guilty about his causing Jane's death. Besides, Eowyn was mentally damaged. But she thought she understood enough to write about the First Commune in the fictional book The Final World Order. However, she was wrong about... almost everything.
You do not have to read the first two books of The Thunder Valley Trilogy... The End Of The Computer and The Final World Order... to enjoy The First Commune.
As long as you know about 'triples'.
There is a small segment of humanity which has a natural mutation of an additional, third strand in their DNA helix. Disease organisms are baffled by their physical makeup, so their bodies remain strong and vital during an exceptionally long lifetime.
There is one more significant difference. Triple women require a donation from two men at the same time to get pregnant. That both complicates their lives, and makes one thing a lot more simple. They tend to have an overabundance of sex hormones, but they can't get pregnant unless they really work at it. So triple women tend to gravitate to the world’s oldest profession.
Thus the genesis of the first commune in the 60's.
Quite naturally, this book is full of bawdy sexuality. Some would call it explicit in a few places. Personally, I think those places are just an honest look at various aspects of human sexuality. I’m sure the authors looked at it that way, especially since they experienced it for themselves.
Yet this book is overarchingly and almost achingly about a great love between two exceptionally deep people. Well, perhaps between four exceptionally deep people. Or you could say six.
It takes over a hundred years an a lot of grand mistakes before the ones who survive finally get things right.
Anyway, reader discretion is advised, and no one who is not truly adult should read this book under any circumstances.
