Query: Not just young adult reading material

I would rate this book in my top 5, if not #1.I've read this book over and over and enjoy it each time.Anytime I want to escape to the youth of being a young boy exploring adventure after adventure I pick up this book.Wouldn't it be nice if we all could escape to new worlds anytime we wanted.I'd like to see this duo of Straub and King team up to write another exciting book as this.
