Mike & Samira have been together for five years and are very happy. Mike has an unusual kink. (view spoiler)[ He likes to play out a fantasy that Samira has cheated on him and he wins her back. It's a cuckolding kink. (hide spoiler)] Years back when he initially confessed this kink, Samira wasn't sure what to make of it. Over time, they've embraced it and found pretty creative ways to act it out. However, those creative ways never involved a real third party. Crosstown Crush tells the story of how Samira and Mike find Bern and how he fits into Mike's kink. 
 Let me say, this book was hot. Incendiary. Incredibly so. It was also a realistic feeling look into a marriage and a relationship with a third person. It's definitely an erotic romance. The sex *is* the story. And it's very well done! 
 I like menage stories, and I like Cara McKenna's writing, so I was delighted when I won an ARC of this story from the author. When I realized what kind of kink Mike had, I wondered if I would end up liking the book. It was really difficult to wrap my mind around how that kink could be a turn on for Mike or for Samira. So, kudos to McKenna for not just explaining the kink so I could understand it but making it scorching hot to boot. I think it says a lot about her writing skill that she can make something that was initially really off-putting to me so compelling and sexy that I didn't want to put it down. I managed to read in it less than 24 hours, and that was a busy 24 hours! 
 As much as I loved the bulk of the story, I was disappointed in the ending. It was more of a very hopeful HFN than it was an HEA. I wanted a bit more resolution before the story ended. Overall, though, it was an excellent read, and it's going on my Best of 2015 shelf. I really want to pick it up and read it all again!
