A new Harry Potter book will be published this summer, author J.K. Rowling announced Wednesday. Harry Potter and the Cursed Child, a new two-part play set to debut on a London stage, will be released in book form on July 31, the day after the stage show’s premiere. The eighth installment is based on a new story by Rowling, Jack Thorne, and John Tiffany. The “special rehearsal edition” script book features Harry working at the Ministry of Magic and raising three children. David Shelley, CEO of Little, Brown Book Group, said, “J.K. 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.”
