Let me get the inevitable comparison out of the way: yes, for me this is way better than any of the 50 Shades (although that's not hard). It's better written (again, not hard) and I didn't want to kill the female lead - although she had her moments. The similarities are startling - ultra-rich powerful man, domination, teh 'dark secret/bad childhood', other woman, etc. And what's going on with this whole 'I'm saying no but I mean yes' trend at the moment? I am already bored of reading books about women who are coaxed, or controlled, into their sexual pleasure by men. Why can't women enjoy sex in their own right without being submissive? Some of Gideon's dialogue is just horrible - any man who came out with, "You need to be f******" during an argument with me would have to get f****** himself. Horrible. And this whole thing of shouting "Mine! Mine! Mine!" during climax? Stop! Stop! Stop! The sex was reasonably written - I got bored of her 'cleft' and his apparently un-deflatable penis pretty quickly, and once again our female lead never got cystisis, and had about 50 orgasms per session - although, for me, not hot. But there was the right amount of it - I didn't have that "Oh not again..." I had with 50 Shades. But my main problem with this book was understanding their motivations. Eva goes from "I don't want him" to "Oh yes I do" too quickly. I was like, "Where did that come from?" And she just runs out on him all the time - too much of a drama queen. I found it annoying. And I felt sorry for her roommate, who is beyond a token character. 
 I would read the next one, and I don't feel like bleaching my brain like I did after the 50 Shades books. However, I could never be hot for a man called 'Gideon'. I mean, really..?
