Which 2016 stage play was co-created by J.K. Rowling and continues Harry Potter's story?

Harry Potter and the Cursed Child is the 2016 stage play co-created by J.K. Rowling that continues Harry Potter's story.

The play was written by Jack Thorne and directed by John Tiffany, with Rowling credited as the story's creator. Its narrative is set nineteen years after Harry Potter and the Deathly Hallows and follows the adult Harry as well as his son Albus Severus Potter.

The original production opened in London's West End in 2016 at the Palace Theatre. The script was published as a book in the same year, labelled the “eighth story” in the official promotional campaign.

Although it continues the characters' chronology, it is a stage play rather than an eighth novel by Rowling. That distinction explains why the original Harry Potter novel series remains seven books.
