On July 31, you’ll be able to buy a new Harry Potter book — sort of. Rowling announced on Wednesday that the script for the upcoming Potter stage play Harry Potter and the Cursed Child will be available in bookstores the same day as the play’s premiere at the Palace Theatre. The script is not technically written by Rowling; its by Jack Thorne, from a story by Thorne, Rowling, and John Tiffany. The version that goes on sale in July will be the one used in the preview performances; any changes before the official opening will be reflected in a later edition. So … that’s basically the same thing as a new Potter book, right? No one complains that Harold Pinter scripts aren’t real books, and Harold Pinter isn’t the former 122nd-richest person in Britain, so there.
