When I was reading the original version of this book, our daughter kept asking me about the story.  Although the book was a bit too much for a younger reader, I had some great conversations about the book with her and the roles teamwork and tenacity had in the story.  I was truly delighted to discover the young readers adaptation.  Our daughter could not put this book down once she started reading.  Brown has a tremendous talent in sharing non-fiction stories in a highly engaging way.  This one is really a winner in both the original version as well as the young readers adaptation!
