I read this book when it first came out and my children were elementary school. This is an awesome tale of friendship by two social outcasts who become the best of friends and feed each other hope for better times. There is a movie based on this book as well and is excellent.
This book, about two boys that don't fit in, joining forces to become more than the total of the two parts is a great story of triumph, love, and achievement. It really caught the interests of my at-risk students. They were able to relate to the boys and my problem readers even volunteered to read.
I teach this novel to sixth graders and I find that for a novel that is 15+ years old it still is relevant to many young adults today.
Funny and heart-wrenching at the same time - a very good read. The film version , The Mighty, obviously is missing a few details (stuff you would notice only after reading it 20x per year). The actors in the film really match up to how you envision the characters when reading.
