Three books, and one more just published!
After a well-received debut with "Three Basic Teas & How to Enjoy Them," I have since published three books in my "Nerd" series about tea, "Tea: a Nerd's Eye View" and "A Nerd's Tea Lab." Just published: "A Nerd Contemplates the Japanese Tea Ceremony."
Oh, there's also "The Great Mississippi Tea Company Cookbook" that I helped put together, too.
