For me, making love always has been intertwined with being in love - even during the times I was trying to convince myself that this could not be happening and this was just a matter of attraction and I was not really falling for that guy. 
 In the same actually way I have never in my life had sex with anybody, while I was in love with someone else - even if I knew that my feelings were going nowhere. 
 Anyway, now I am happily married for many years and these thoughts are just part of my past and my younger more adventurous (not really) self. I have already chosen my prince charming and I am happy that I give love and I receive more love. So, all is good. 
 I am giving you this long introduction so that I will make you understand that I normally do not like romance books where the two people who are falling in love keep having sex and serious relationships with other people before they share their feelings. Especially when these two people are in their mid thirties going to forties and they are supposedly mature enough to know their feelings and to be responsible for their actions. 
 Somehow the description of the relationship between the 35 years old Kate and the 37 years old Trey has worked in this book. They started as a "boss-employee" relationship, then it moved to a "best friends" relationship and finally they become lovers. 
 We are talking here for a really slow-burn thing expanding in a two years period. Boyfriends are coming and going, girlfriends are coming and going, sex with others regularly. Trey has been a very naughty kinky boy. Kate is more reserved and she is having sex only with her boyfriends/husbands-to-be. 
 Trey is flirty always, staking his claim then taking everything back and the situation is all the time in a gray zone. I suppose the problem is Trey, throughout the book. Firstly he has a policy of not fucking with his employees, later on he just wants to save his company and sex with Kate would complicate things, after that Kate is too engaged and too prude to have anything to do with him, then he was thinking that maybe she is too good for him. 
 His secret life and the way he enjoys sex are his main problem. This is something that we learn almost in the middle of the book, but we always suspect. Kate will find out later when all the secrets have to be revealed and she has to make up her mind because at this point the ball is in her court. 
 I was pleasantly surprised with this book. I was expecting a full smutty book with your usual type kind of guy, cocky bastard foul mouth arrogant jerk. 
 I couldn't be more mistaken. The characters have depth and substance. 
 Trey is a lost soul. He loves his employees and he is one of these types that he prefers to let his company sink than fire anybody. He is of course a playboy, but he is very private. 
 Kate is the nurturing type. She will offer Trey an anchor. She is loyal, trustworthy and real to herself. When she thinks that her relationship is not going anywhere, she will end it (Her ridiculous fiance will steal the show in the first half of the book). 
 Both of them will learn to coexist and to communicate. Trey will learn to slow down and think, Kate will learn to let loose sometimes. 
 The sexual tension is high. From the first impression the two of them have for each other. She thinks that he is so good looking that he should be illegal. He thinks that if he had wanted her, he could have had her. 
 Overall I really enjoyed the book and I will try more by this author.
