I am going to put it out there. This series could be summarized by three things: Eating, lip-biting, and inner-goddess nonesense. Oh, and rough sex of course. 
 I will completely ignore the first half of this book because I dont even remember it. I read it, got bored, left the book aside for over a week and only when I was bored enough to pick it up again did it get better. Honestly, I only remember thinking it was a bonus track of the first one, a repetition of the same things, scenes, problems, streams of consiousness, all of it. The one thing about the begining I remember being bothered with was the fact that the second only takes place a couple of days after the first ended (what's up with that?). I would've rather if some significant time had passed so we could have a proper reunion. 
 I will not discuss the hot aspect of the novel cause trust me, that is all goooooooooood. And props to the author for making Christian Grey probably the most irresistible character I have read about --and I did not even picture Ian Somerhalder when reading it! But really, even with all his flaws... damn dude. 
 All that being said, in the second part I could finally see some development and purpose to the second book, yet I found like it did not really have a thread in the storyline, it was like each chapter introduced some random issue (Ex. Charlie Tango problem) that maybe served to some purpose at the end but seemed out of the blue. I am not saying I want some predictable storylines but one that seems to fit with what is happening.
