I finally finished 'The Harrad Experiment'. It got interesting in the end because it became another utopia book. The group fantasise about creating a new society in America based on their principles. These principles included everyone being allowed to live with their partner for as long as they like before deciding to get married and that if they have children - they have to get married. Also once they are married divorce is incredibly difficult because once they divorce the children are adopted and the biological parents never get to see their children again. Very interesting but not very practical
I didn't like their idea of a group marriage where you sleep with a different person depending on what night of the week it was. That doesn't seem that pleasant and I know from books like 'Getting back together'by Robert Hourier that it is a nightmare.
