Mason is tough in his book reviews. I have not read the new book from Brier/Ciaffone. I intend to buy a copy but will probably skip it if Mason gives a review under 5. I know that's acid logic but what can I say? I'm thinking that 6 is about right for the over/under for his review score. That's based on comments regarding the articles Jim wrote and comments about the book from other posters so far.
