I read this story and it has a great inspiring message. It is a religious story, I didn't realize it at the time of accepting the review. Dudley is in the Church choir, they sing "He's got the whole world in his hand".
Honestly my 7 year old did not like the book. We are not a religious family, so she had no interest in church, prayer, etc. She did like that Dudley got to the solo by signing though. The book was just too religious for our taste.
I'm not sure the recommended reading age of this book. It is most likely geared more for younger kids though. If you are enjoy a religious natured book, then this is an excellent book to read to your child. The idea of treating everyone equal is very important!
The kids in the choir are called the Children's band. They have a great website, where you can meet the inspiring kids including Dudley.
The book retails for only $8.00. It is a really nice softcover book.
