Just a little extra note - My 79 year old mom recently passed away (Summer 2022), and she volunteered at our local Friends of the Library at the nearby community college.The books were just going to go to a book recycler, so I volunteered to sell them. All profits from this sale will go towards a scholarship created in her name at the local community college
We think she would get a giggle out of where the funds selling these books comes from, and she was never one to yuck your yum for what is on your reading table.

I think of this genre as a top shelf book, as that is where some books were kept out of the kids reach in our house growing up. I attempted a few of the books. One comes to mind is Fear of Flying by Erica Jong. I read a couple of chapters, and ummm, put it back. I did read Nakoa's Woman all the way through, with the help of the street light shining outside my bedroom window. That was also my method of Nancy Drew books as a middle schooler, so no alarms were raised when this book crept in the stream of light coming through my curtains that my bed post held open.
