This is set in 1959, written in 1960. It was interesting seeing the past and past views and behaviour, and the story may have been surprising in the past, but thanks to the swinger movement and orge parties and the rise of porn and news of human trafficking (which is far, far worse than this story), this is not as shocking as it could be for the modern person, or at least not to me. I'm sure people of the past may have fainted from this but for me, I just wanted to slap them all in the face.
It also takes a very long time for any plot to evolve and shine through. I was bored at times reading this. Though it was nice to see the main character evolve, to see her go from a queit, timid woman who fit in the 40/50s to the equivalent of a modern woman of that time, though she takes her own sweet time.
Interesting to see the past, but the story is boring.
