When I borrowed this book, I noticed a plethora of study materials related to it. Strange for what appeared to be a book geared towards 6th graders, but I understood after reading it through. The story is about a knight who chases adventure, leaving his family and kingdom to fend for themselves. He falls asleep in his armor and awakens to the unusual problem of being trapped in his metal protection due to rust. The knight embarks on a quest to remove his armor and ends up at a castle. Each room of the castle is designed to teach the knight something about himself, and each time he learns a lesson the door out appears and part of his armor disintegrates. The book does a nice job of illustrating how humans create virtual armor for themselves and gives methods to break the armor and therefore become a better person. The story got sappy at times, yet was still extremely enjoyable and recommended.
