This is the Sex Age, and E.L. Jamesknows how to make money from it.
After the huge success of her first trilogy 50 Shades of Grey, James decided to write the book from another angle.
The original story was told from the point of view of the story's heroine, Anastasia Steele, and this time, the story is told from the hero, Christian Grey's eyes.
The new novel, titled "Grey: Fifty Shades of Grey As Told by Christian", was released on the 18th of June, and has already sold over 1.1 million copies in paperback, digital and audio forms.
The demand was not exactly expected, and publishers Vintage Anchor have ordered a fifth printing since the release.
