Query: THE BEST BOOK EVER WRITTEN!!!!!

There aren't many books that can recieve 5 stars from everyone, but this book deserves it!!! It is my favorite book in the entire world ; well-written, capturing, adventurous ; this book has it all!!! It should rate #1 on the sales rankings, the only problem is not enough people know about it!!
