I'm not really sure how to rate this.
The reintroduction to Mark was an eye opener. I didn't expect I would instantly like him, in my mind he had some redeeming to do before I let him into my good graces, after his shenanigans in book 1. But when we meet him this time around, we meet this heartbroken, kind of pathetic guy, that's ready to make a big change for the better, and he does. And he keeps this up for a good while through the book, before his personality turned, in lack of a better description, confusing. At times I really didn't understand why the guy did the things he did.
Then there's the "side plot" with Christian and his struggles, we even get a fair bit of page time from his POV, and it takes some of the focus away from our main couple. This book wasn't, in my opinion, big enough to spend so much time with Christian.
To top it all of I'm not a big fan of insta-love, purple endings, or stupid misunderstandings.
On the completely different hand, there's also things I really liked about this story.
One of my favorite "kinks" is the superstar falling for the regular person. Just the possibility of this happening makes all my teenage/tweenage fantasies seem a little more reachable, and it makes the 13 year old in me really happy ^.^
And Zane, our heartthrob action hero, is solid, down to earth, and genuinely sweet.
Mark's family is also a comical relief, specially Reid, Mark's brother, made this book fun every time he appeared on page. I wouldn't mind reading his HEA with his promised actress ;)
