Although his best-known book is Shrek!, all of his books have a wonderful quality. My kid especially liked Sylveser and the Magic Pebble. When I was on tour for my first book, Circles of Confusion, an alert bookseller gave me a copy of hisCDB! (See the Bee), thinking I could use it. Could I! The main character in Circles deciphered vanity license plates, which meant I occasionally had to make one up. CDB! was extremely helpful in making me think of alphabet letters as words.
