Well, 'Fifty Shades of Grey' has its roots in 'Twilight' fanfic. You see, the basic idea of the relationships and some character traits were borrowed initially. However, 'Fifty Shades' evolved to be a very different kind of story, focusing more on a different kind of relationship dynamic with a strong emphasis on BDSM elements, which is quite different from the supernatural - based love story in 'Twilight'.
The 'Fifty Shades of Grey' series actually began as 'Twilight' fanfic. The author took the inspiration from the characters and some elements of the 'Twilight' world and then re - worked it into her own unique, more adult - themed story in 'Fifty Shades of Grey'.
The connection between 'Fifty Shades of Grey' and 'Twilight' fanfic is quite significant. 'Fifty Shades' started as fan - created work within the 'Twilight' fandom. It took the idea of a brooding male lead and a somewhat naive female lead from 'Twilight'. But then it branched out into a story that explored themes of dominance and submission, which is a far cry from the vampire - human love story of 'Twilight'. This transformation from fanfic to a global best - selling series is quite remarkable in the literary world.
