To carry it further, I just remembered a short novel published many years ago that was a literary sensation. "Bear," by Mariam Engels (I think was her name.) It was published by Random House or Knopf, one of the biggies. It was about a normally experienced woman who went to live alone in a cabin on an island in a lake in Canada. The owner had a docile bear chained to a stake and sleeping in a near-by log crib. Yes, the woman has intercourse with the bear. But the progress to that was literary genius and erotica of the purest type. The irrestible, inevitable lure to the forbidden, but possible. And she was contemporary woman. In fact, I think she was your run of the mill librarian. (Don't trust my memory.)
Reviewers were hard put to explain why this story was so damn good. The mere idea was mind boggling. The path and resolution was utterly believeable. There was no moral, psychiatric, social judgement available to place on the fictional woman or the author. Not any that an intellectual mind could accept. She out-flanked them all. The author gave us a lightening flash of literary genius of the highest rank. The reader could only marvel. Find it, read it, put it in your library.
