I haven't read any lately myself but there sure are alot of them available this time of year.
A quick visit to Amazon yielded 101 books on bbq including:
Ray Lampe's "BBQ All Year Long"
Mike Mills' "Peace, Love and Barbecue"
Dottie Griffith's "Celebrating Barbecue"
Sunset Books' "Building Barbecues and Outdoor Kitchens"
If any readers would like to offer more suggestions for the bbq reading list or even a book review of your favorite bbq book, your contributions are welcomed.
