Query: Book for beginner or advanced

Bought this book yesterday and have already read 1/2 way through. It is great,,, starts off with the basics the router, bits, whats avaliable pros and cons. You name it this book has it. I am just starting out and I learned more in a day of reading this book than I thought was possible. A MUST for the beginner like myself.
