People have complained about the quality of the writing in Fifty Shades of Grey, but I would argue that E.L. James was masterful in her use of erotic cues and storytelling that stimulates all the senses.
At times Ana is not sure how she feels about Christian or the relationship, but what she does know is that getting so much focused attention from a hot, rich man turns her on. And apparently reading about it turns on the reader as well.
Even more than the book themselves, though, I am fascinated by the whole Fifty Shades phenomenon. So when I learned that there was a magazine devoted to the subject, I knew I owed it to our readers to go exploring. Oh, the sacrifices I make for my job.
