Query: Excellent book!

I read this book in my fourth grade class, about twelve years ago. I loved it in class, and went on to read the rest of the series (it's a trilogy, if I remember correctly). The storyline is compelling, but not confusing. It poses an excellent moral dilema for kids--is it better to do what you know is right and break the rules, or follow the rules and allow an innocent animal to suffer?
