Radical Brewing is actually by Randy Mosher. It is fairly light on recipes, and concentrates more on historical brewing techniques, ingredients and how everything fits together. It is a good read. A similar book is Brew Like a Monk by Stan Hieronymus. It contains a few recipes, but describes in detail how to recreate a trappist style beer. I saw a book at Chapter's last night called Brewing Better Beer by Gordon Strong which seemed pretty good, as well.
There are a million beer recipes on the internet, so personally I think a recipe book is less useful than a book which shows you how to formulate a recipe. I suggest checking out the recipe section on homebrewtalk.com - find a style you like, pick a recipe, read the feedback on the recipe, brew it up.
