I don't know what it is about Young, her writing, and her characters, but whatever it is, she's got it! I simply could not put this book down. Something about the characters and their romance compelled me to keep reading, dying to know what would happen between them next, and how their story would unfold. Both Caine and Alexa's personalities jumped off the page. Couple that with one heck of an electrifying romance filled with explosive chemistry, well, you've got yourself a winner right there. Sure, Caine can be considered your typical rich, alpha male and Alexa is your go-getter who tames the beast, but their story is so much more than that. Their relationship is so much more complicated, connecting on a deeper level, not to mention they were highly entertaining - I couldn't get enough. 
 Like I said, Caine sounds like your typical billionaire Mr. Irresistible, complete with brooding moments and swoon-inducing sexual escapades, but he is also a guy with a troubled past and a soft spot for sweets and old-timer neighbors (who I also adored). It takes quite awhile to crack this guy's shell and although I never cared for the back and forth jerkiness of most of the male characters out there, for Caine, it worked. For Caine and Alexa's relationship, I understood it. Sure, he would work my nerves quite a bit, but Young made it so I never truly hated the guy, which I didn't expect at all. 
 As for Alexa, I have to give that girl snaps. When she is determined, nothing and no one can stand in her way. Caine truly puts her through the ringer while she works for him, and I loved that she never felt intimidated by him. Her feisty, "take no crap" attitude made me love and respect her so much. Her relationship with Caine is so complicated and the tension between them was truly palpable, I loved it. She put up with all the crap that Caine makes her do, but she does it all with flair. I also liked how good she was at what she does. She may be just a PA, but she's excellent at it and so much more. It was cool seeing her true skills come out and, through that, discover that she truly wants to do with her life. 
 Hero is one of those books that just grabs you right from the first page and has you flying through the pages, never letting you go until the very end. Even then, you're seriously begging for more. Young has definitely outdone herself with this book and this might just go down as one of my favorite reads of 2015.
