This story does have some hot and steamy sex scenes. But honestly, that's about all I enjoyed about it. Elisa and Maxim were lab partners in college and Max was known as the playboy around campus. He wanted to get Elisa into bed for whatever reason (all we know is that he says there was something about her that was different), while Elisa - who had a crush on him - kept him at an arm's length because she didn't want to hurt. The book picks up years later when Elisa's had a little bit of trouble and Max feels like he needs to return to her in order to have her.
The characters were incredibly hard to like, especially Elisa. She still has a crush on Max and wants to know what's it like to sleep with the man, but she begins making him "prove" that he's changed and isn't he playboy that she knew him to be in college. But then she's just flat out annoying and a pain in the ass. Max ends up putting up with a lot of crap from her, pleasuring her over and over without taking release or pleasure for himself (part of her rules) and she continues to make it work for it. While it may have started out as a fun game, and could have remained a fun little game which pleasured both partners, Elisa became unlikable and just outright spoiled in a way. Max puts up with it because he refuses to believe that he's in love with her, though he nearly says it aloud a few times. We learn he has a valid reason to be scared of falling in love, and eventually he comes clean to explains why and we finally feel like there's some kind of connection between the characters.
However, the ending is completely rushed and non-realistic, and the author throws a life threatening problem into the mix which is resolved in like three pages, so it's not really life threatening, and honestly doesn't really add to help move the plot along. I actually stopped reading about halfway through the book and started skimming until I got to the end, because the characters were just flat out annoying and I had no connection to them no matter how hard I tried.
This book had lots of potential, but just didn't do it for me.
