Today's Blind Items - The Underground

This author is foreign born and definitely A list. Many of their works have been turned into movies. Some have been successful, and some not so successful. This author has courted a lot of controversy behind the scenes in the literary world. It is what they do underground though that should be disturbing. They have long been known as fans of anything incest related and much of their early work revolved around those themes. Obviously those didn't really catch on with publishers, so changed the characters from sister/brother to boyfriend/girlfriend and then it got picked up. The author is said to have one of the largest collections of actual incest p*rn. Not just online files, but DVD's and VHS tapes they have amassed over the years. The author and their partner have been known to go to swinger clubs where they roleplay incest scenarios with other participants. The author and their partner refer to each other as sister and brother. This goes really deep and very dark.
