First on the agenda, is star rating. I have been bouncing back and forth between three stars and four stars. I really want to give it four stars, but I also think it kind of deserves three stars. In the end, I'm going to go with 3.5. This has been the hardest book ever for me to rate. I have been pulling my hair out!Our protagonist Calla is kind of a b*tch. And that's part of the reason why this book frustrated the crap out of me. I thought she was extremely selfish. Who in their right mind plays two amazing guys against each other? She only thought about her own feelings and what was in it for her. Some might argue that point, but I really think she only considered others' feelings when it benefited her to do so. And I really, really hate people like that. And then there was the issue of the love triangle. She was just as attracted to Ren as she was to Shay, if not even more so. Yet, clearly from the author's perspective, Shay is the one she is meant to be with. So why then, am I more of a fan of Ren? I don't get Calla's attraction to Shay at all. They have absolutely no chemistry. And this really ticked me off! It's like the author had no clue what the heck she was writing! And neither did her editor, obviously. As far as plot goes, I thought the book was amazing. Pacing was perfect, it had an awesome, suspenseful, and twisting storyline. I loved the setting and descriptions, and I usually hate cold weather settings. I think it was a very memorable book, I just found the characters' motivations to be off-kilter. And that is pretty much the reason I read to begin with. When it all comes down to it though, I did enjoy what I was reading, I was just frustrated as all get out. It will be interesting to see where the author goes with the story in the next book, and if all my complaints in this review will become a moot point. It's possible. Most of you have already probably read this book, and that's okay. I just wanted to get my opinion out there, as there are a lot of books that I need to read to catch up with everyone. If you haven't read it yet, I do recommend it and I would definitely love to hear if you were irritated by the same things as I was. Be sure and let me know.
