Query: A must read!

This was my first introduction to Chistopher Moore's work. I laughed so hard I cried. My son gave me this for Christmas and for days after my family found me laughing out loud or chuckling to myself as I recalled passages from the story. VERY entertaining! I have since purchased most of his other books, all very good. But I like this one the best.
