Kelsey is such a Mary Sue that it ruined the book for me. She is unrealistically perfect in every single way, which makes her really hard to get into. Real people have real flaws; hers are that she's too gorgeous and she's too much of an "angel". Really? She was boring, very flat, and she got annoying.
Jordan, on the other hand, was way on the irrelevant side. She was there as the romantic interest, obviously, but she was equally boring. She wasn't of much use to the story. Aside from the sex scenes, she was extremely unnecessary.
The characters didn't go through any significant character growth that you would expect at the end of the book. I know this is an erotica, but damn it, there is still a need for character growth. On top of that, the sex scenes (if they're any good) should say something about the characters. These were way too generic.
The stalker thing only pushed this to the limits of too dramatic and really was a lame way to include some "intense" conflict/danger that would cause Jordan and Kelsey to get their heads out of their asses and admit they care for each other.
And don't get me started on the testosterone-filled, bullshit scene in the end between Jordan and Paula. Am I really supposed to take that seriously?
This book was a big bunch of nope. I waited years before actually buying it, and I'm disappointed I wasted the money.
