Overall I really liked the story by the end. I think it took to the end of the story to really be able to step back and see where we were led. I will admit that I wasn't so sure about it at first. Everything was happening really fast. I thought that Elena and Raphael's relationship was odd at times. It seemed at first that Elena was interested (well she was but knew she shouldn't be) and was determined to keep Raphael out of her mind and stop controlling her, and the next moment she's ready to sleep with him. I think it almost would've benefitted being told in 1st person so we could understand more of her thought processes at these moments. 
 I also found Raphael strange at times. He would seem normal sometimes, and then unusual at other times. I did have to remind myself that it's because he's an angel, he's not human therefore not subject to their same thought patterns. 
 You can definitely tell that this is a series. There are a few questions left unanswered that hopefully will get answered over the course of the now 8 books that will be in the series total. So, along with a lot of the storylines being left open for furture books, I felt that was the same with the secondary characters. I suppose we will get to know more about them as we go along than we did in introduction. 
 I did find the Uram storyline to be interesting and well thought out. Although, I was a little confused as to why it was brought up so early in the book when nothing could even be done about it until more than halfway through the book. I thought that it could've been intermingled with the rest of the story a little better so it didn't feel like he was just thrown in as a threat towards the end. 
 I would have also liked to have gotten more information about the final events of the story. I don't want to give too much away here. If you are new to the series and haven't read anything else about any of the other books then you will appreciate the ending. But regardless, maybe we will learn more in the next books. 
 I do look forward to continuing with this series although this book only received 4 starts from me, the end was so satisfying for me that I feel that this world will just keep getting better and better. Until then!
