The novelist has announced that the 7th (and last) installment of the Harry Potter series, "Harry Potter and the Deathly Hallows" will be published July 21. Worldwide sales of the Potter books have topped 325 million copies. The film seriesfrom which Rowling enjoys a cut of royalties and merchandisin has already grossed $3.5 billion, and there's no doubt three more movies to come.
