I read it. And it all felt wrong. Like "call-the-police-now" kind of wrong. 
 Initially, Erik's just cold. He's got an issue behaving professionally. He's bringing women home for one night stands knowing that the young gymnasts can see what's happening and it doesn't send out a great message. Well, rakes are like that and we have forgiven them for such misbehaviour in a lot of cases. Problem is it doesn't stop here. He's cold, domineering and mean towards his gymnasts and cannot behave normally around Brie. His preferential mis-treatment towards her doesn't go past anybody's eyes and frankly, puts the reader off. Ya ya, indifferent hero makes for a great challenge. You can have this challenge all for yourself. I am just reading the book because I learnt from a great person that every author deserves your attention if you've ended up picking up their book. 
 My noble promise bit me in the ass at the end. 
 I don't understand what is the problem with asking for consent?! 
 (view spoiler)[ While making out with Brie after a private yoga lesson, their lady instructor comes back to join in a gross threesome. All while Brie never even agreed to it! Heck, she wasn't even asked beforehand! (hide spoiler)] 
 Some may like such a morally ambiguous story. I really didn't. I wouldn't even call it ambiguous. It was sexual harassment, plain and simple. What kind of generous and truthful love makes you go so emotionally cruel towards your partner. And so we add another crime to the list. Emotional abuse. 
 I suppose I should call the guy some choice profanities. But I am so disgusted, I don't think he deserves any more attention.
