Porcine Perfection
is One Chatty Farker
Don't have it but I've heard plenty good of the Adam Perry Lang's Serious Barbecue book. I think it'll be perfect for him. You can preview it on Amazon:
Serious Barbecue: Smoke, Char, Baste, and Brush Your Way to Great Outdoor Cooking: Adam Perry Lang: 9781401323066: Amazon.com: Books
I was going to suggest this. I have it and reference it all the time.
