50 Books Inspired by Fifty Shades of Grey

Sean Black's A Million Shades of Green: The Real Story Behind Fifty Shades of Grey "will take you on a journey into the hidden world of porn fan fiction, where books originally written for, and aggressively marketed towards children and teenagers by writers such as J.K. Rowling and Stephenie Meyer are given a violently pornographic twist before having their 'serial numbers filed off' and being sold on as original fiction."
