Fifty Shades of Grey by E L James
This is my ‘best seller from a genre I don’t normally read’, I only read it to say I had so I could fully argue about how bad it was as a representation of BDSM culture. Safe to say, it is terrible, but I could see why people enjoyed it. It was easy to read (unless you happen to enjoy good writing) and was popular enough that you could read in public without being judged to be a member of a crazy sex club.
It puts BDSM in such a terribly abusive light, there’s been so much written on it, there’s no need for me to go into it. I read it, it’s awful, end of story!
