Query: If you want to know Ruby this is the book for you.

This review refers to the 2nd edition (2007).If you have seen a few games and are lost, this is the book you want to get. It explains everything from the smallest detail to the history of the world cup. If you don't know the difference between a ruck and a maul or you have no idea what a pitch or a try is then buy this book. Everything is explained in a simple and easy to understand manner.But then isn't that how all "for dummies" books are written? Well this one is written by people who play and know the game and have an idea how hard it can be for an American on the outside looking in to grasp the game.I highly recommend this book for both those new to the game and those that have been just using Rugby as an excuse to pop down to the pub for a few pints.
