You may know this already, but I just learned from NPR Books that Daniel Pinkwater will be publishing The Neddiad in April 2007. In the meantime, his original draft is being released a chapter at a time on Pinkwater's website. Chapter 18 published for Thanksgiving also has an audio version.
The Neddiad is the adventure of Ned Wentworthstein, who moves from Chicago to Los Angeles with his family so they can "eat in a hat." They ride cross country on the famous Super Chief train with a stop in Flagstaff. In Pinkwater tradition, it is a strange and humorous tale.
On the website, Pinkwater describes his writing process and uses terms that I had not read in a long time -"IBM clone computer." He also says that he has the book on two 3.5 inch floppies. He goes on to say that the hardcover will have slight changes and illustrations not seen on the web version. He hopes we will all buy copies. I am sure many libraries will.
