It started out as a three book series. Then social media took over and turned the series into a must read, bestselling story. Next, came the movie. Then social media took over again. Now there's a bestselling soundtrack according to Twitter, https://twitter.com/AOL/status/568803770286501889/photo/1.
I can't image there is someone who hasn't at least heard about the books, the movie or the soundtrack, but in case you haven't, here's a link to the books on amazon.com, http://www.amazon.com/Fifty-Shades-Grey-The-Trilogy/dp/0345803485.
I did read the first two books of the series and gave up on the last one. Don't know why exactly just got a bit tired of the storyline. I bought all three books at one time so it may have been better to purchase them and read them one at a time. The movie has gotten mixed reviews so I think I'll wait for the release on blue ray to watch.
It's making history in more ways than one. The marketing machine on Fifty Shades of Gray has made it a phenomenon. The author may never have to write another word.
