Thank-you for bringing this book to our attention. We do have a book section (towards the bottom of the home page) and I've already reviewed the book Thread/post HERE
As you mention it is American based but I also agree that it has fine contents. I'm not sure where you sourced the book from but the link you put in gives a much better price than I found. Well worth the price.
You learn something new everyday, I didn't realise play sold books, when I used to buy from them it was just computer games and dvds. I'll have to check them for books in future as it looks like they are competitive.
