Even as an audio book, this was a chore to get through. It's a tale of a future with super human artificial persons (the titular Friday), violent city states, and coporatized family structures. Oh, and lots of cringey sex talk. I suspect Heinlein was a swinger who wanted moral justifications for whatever dark seeded perversions he held. Unfortunately, he writes like a seventh grader and also has a seventh-grade boy's understanding of women. So dumb.
