A new prequel to "The Godfather" is in the works. And before you start groaning, bear in mind that it's only a book, not a movie -- so far.

Grand Central Publishing announced Wednesday that the novel would be written by Ed Falco, an award-winning author and poet. The book will be set in New York in the 1930s and is based on an unproduced screenplay by Puzo, who died in 1999.
