This is a tough review to begin so I think I should start by saying that you should go now and get this book because this is a great book to discuss with others who have read or are in the process of reading it. I know that there is a lot of hype surrounding this book, and I understand why. It is a great read with colorful characters, exotic landscapes, and unsolved mysteries. The writers did a excellent job of propelling the story forward while developing the characters.
I will state that there is one minor downfall for me and it is the only reason I did not give this book 5 stars. The character, Lilac, had some developmental shortcomings in the written sense. Don't get me wrong, I loved her after the growth and adaptation she went through, but I think that in an effort to present her to the audience in the beginning as the debutante, she was made just a little to self-conscience. It was the only critical thing I can say however.
The landscape and setting for this book were the stars of the story and I wish that more would've been done with the actual local wildlife. This book reminds me (vaguely) of the old science fiction movie Enemy Mine, which is a classic to me, but for young adults and more romance. I would love to see this book adapted into a movie and can't imagine that someone out in Hollywood land isn't already in the process of trying to procure rights. So I highly recommend you go grab the book now before the mad rush to read it before primer day happens (hopefully).
