From The BBC:
An eighth Harry Potter book is to be released this summer – containing the script for a new stage play telling the wizard’s story.
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.
It sees Harry as a father and an overworked Ministry of Magic employee.
The play 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.
It will pick up the story 19 years after Harry was last seen in Harry Potter and the Deathly Hallows, waving his two eldest children off to Hogwarts.
