An even raunchier new book in the 50 Shades Of Grey erotic trilogy hit the bookstores on Thursday.
Titled Grey, it tells the love story between Christian Grey, a troubled business tycoon with a penchant for kinky sex, and college student Anastasia Steele, through the eyes of Christian.
Fifty Shades Of Grey and its two sequels Fifty Shades Darker and Fifty Shades Freed sold more than 125 million copies worldwide and was published in 52 languages.
For fans of the books dubbed "mummy porn", this new addition is not to be missed. For the rest of us, it may be more fun reading reviews of the book:
Grey exposes the rich, debonair and controlling Christian Grey as an "utter psychopath", says Jenny T Colgan, whose review of the book appeared in The Guardian.
She says: "The first book was a rather fun and fairly mild portrait of a woman's sexual fantasy. Yet it is almost impossible to read Grey and not assume the narrator is going to end up in jail."
The Economist makes a similar point with its review titled "I'm a creep".
Romance writer and book reviewer Sarah MacLean warns in The Washington Post that "Fifty Shades Of Grey As Told By Christian is for fans only".
While the book follows the familiar plot in the original Fifty Shades Of Grey, and part of the sequel Fifty Shades Darker, it also adds in details about Grey's childhood. Mostly though, it is filled with Grey's sex-crazed, predatory thoughts about Steele.
MacLean's verdict: "Grey is dark and unrelenting and far too serious, like Mr Grey. No one can ever say that James does not understand her characters."
A former defender of the trilogy could not handle the reversal of roles. Slamming the book in The Telegraph, Rebecca Reid called it "less sexy than an eye test".
Reid writes: "it turns out that Christian Grey isn't just fifty shades of f***** up (there's a whole thing about a peeled ginger root in a place that a ginger root should never be) but he's also about a million different shades of sexist."
She adds: "There should be no room for it (sexism) in the real world, let alone in our fantasies."
Not everyone was dismissive. The Mirror was writing for the books' fans when it listed five classic scenes, and compared Christian and Anastasia's experiences.
There was the first kiss, and the first time they had sex, and... well, you can read about it here.
And for those who are not willing to shell out for the book, this alternative Telegraph review conveniently gives a tongue-in-cheek outline of each chapter and the "best lines" from each.
