This was a hard book to rate. There were things I absolutely loved: the budding romance, learning to trust, the hunt for the library and all the clues leading up to it. But there were also things I just didn't care for: the truth about the parents, Whit's betrayal/forgiveness, the sister storyline. I know that without the things I wasn't a fan of, the story may not have been as interesting and it would have been hard to get to the same place at the end - which was an amazing and beautiful place. The ending was just about perfect, and it made the parts I wasn't quite a fan of worth it in the long run.
