I loved this. I want to shout that from the rooftops. 
 I went into this with low expectations, for some reason I expected it to be very movie-like (since the movie IS about to come out). But that wasn't the case. It was very well written. 
 I really appreciated the emotion that the main character, a boy, showed. Typically we don't see that emotion written for a boy. It was refreshing. 
 I know that we'll probably learn what was in the letter in The Power Of Six but I really wish that that had been included in this book. Also, I'm very surprised at how quickly this book was picked up for a movie. Though, once reading it it became obvious that it would make a great movie.
