This book does give you a good historical lesson on Pale Ales. If you truly love Pale Ale, I do recommend this book; but it is quite factual and somewhat boring at times.
As a homebrewer that brews extract beers, I was pleased that the book did offer extract recipes; however, the number of recipes was somewhat limited.
I certainly do not mean any disrespect, but I was disappointed by the book's excessive use of exclamation marks. In my opinion, they give the book a sarcastic tone.
However, if you enjoy Pale Ales as much as I do, relax, get this book, and have a homebrew.
