Caine Carraway is a self-made man. Rising from a tragedy, he becomes a successful financial mogul in Boston. He's a colossal jerk, too. Alexa Holland is an extradordinary personal assistant and her past includes a link to Caine and when he finds out, he does something crazy and improbably and hires her to work for him, even though he's been incredibly cruel and unprofessional to her. 
 This story could have easily fallen into the billionaire-virgin variety, but it's really Alexa who is the star of this story. The story is told from her point of view, and she's had some bad stuff happen in her past, too. I found her to be very likable. She has a sense of rightness and I like how she dealt with Caine and his bullying ways. 
 There weren't many surprises for me in this, it's the classic, "sex without a relationship" story that always ends up with someone falling in love. Even Caine's reasons for being so closed off weren't that much of a surprise, although I did wonder how someone as together as he appeared to be hadn't dealt with his feelings about his past, unless he was still engaging in the behavior. It made him appear weak and that was another blow to his attractiveness. I just didn't find him appealing, but Alexa made up for him. 
 This is was my first book from Samantha Young and I did like the writing style and the story kept me turning the pages until the end, so I'm rating this four solid stars. I'd read more from this author in the future.
