Read this book so many times as a DTB, and finally got it for my Nook a little while ago. This is a guilty pleasure book for me, but there's nothing wrong with that. Yeah this book isn't the most intellectually stimulating, but it's not supposed to be, same goes with the language used. It's not supposed to be the same caliber of a book like one written by Stephen Hawking. It's a simple, quick and fun read. That's why I love it.
