article: A hardback edition of Harry Potter and the Cursed Child - Parts I & II will be released on 31 July, the day after the play has debuted on stage in London. Following Wednesday's news, pre-orders have propelled it to number one on the Amazon and Waterstones book charts. The play sees Harry as a father and an overworked Ministry of Magic employee. The script is from an original new story by JK Rowling, Jack Thorne and John Tiffany. Harry Potter and the Cursed Child will tell the "untold part" of the boy wizard's story, including the story of the lives of his murdered parents, Rowling has said. In a statement, Waterstones said it expected pre-orders to break all records and were already exceeding those for Harper Lee's Go Set a Watchman over the comparable period. Last year, Go Set a Watchman was the first title whose pre-orders reached the heights of those for Harry Potter and the Deathly Hallows in 2007. James Daunt, chief executive of Waterstones, also told Radio 4's Today the "prospect of an eighth volume is extraordinarily exciting". "I challenge the notion that plays aren't a fabulous, an extraordinary, thing to read - that bloke Shakespeare wrote a few that were worth it, and indeed many of our modern playwrights do too. "Because theatre is a very local phenomenon, play scripts do sell well, they just do so in the immediate locality of the theatre. They are wonderful entertainment, more people should do it." The special rehearsal edition of the script book will comprise the version of the play early in the production's preview period and is therefore subject to being changed before the official opening. The edition will, therefore, only be available for a limited time, said the publisher, "to be replaced by the definitive collector's edition at a later date". David Shelley, chief executive of the publishers Little, Brown Book Group said on Wednesday: "We are so thrilled to be publishing the script of Harry Potter and the Cursed Child. "JK Rowling and her team have received a huge number of appeals from fans who can't be in London to see the play and who would like to read the play in book format - and so we are absolutely delighted to be able to make it available for them." The play, Harry Potter and the Cursed Child, has already proved to be a success with an initial round of 175,000 tickets sold in October within 24 hours of booking opening. Producers released a second batch, available to fans who had registered for priority booking. A third set is still to go on sale but the date is yet to be announced. Previews of Harry Potter and the Cursed Child begin in May at London's Palace Theatre, with both plays set to open on 30 July. Jamie Parker, currently starring in the West End show Guys and Dolls, will star as an adult Harry in the production.
