There were some issues I had with this. First off the way that A spoke. No teenager speaks the way he does. It was too mature for how old he was and I just couldn't believe it. If anything in a story should be believable it should be the main character. My next biggest issue was the serious case of instant love. A knew Rhiannon for maybe 6 hours and he knew he was in love with her? I think that is kind of forced. No way can anybody fall in love with someone after 6 or so hours. It just does not happen, you can't know anything about the person that has any substance at all.
The one part of this story I liked the best was the end. Not because it was over but because of how the story ended. I believe that A made the right choice in the end, both for Rhiannon and himself. I think the decision itself showed how much A cared about her because he knew he wouldn't be able to be what was needed.
While this story may not have been the one for me I will definitely be checking out another one of his books.
