Author J.K. Rowling announced a new extension of her beloved Harry Potter universe, with a London stage play entitled Harry Potter and the Cursed Child. The play will debut at the Palace Theater in London's West End next summer, although the author won't divulge any specific story details. Here's what she had to say in a series of tweets earlier today about Harry Potter's immanent return on stage.

"Today is a very special day for two reasons. Firstly, Harry Potter and the Philosopher's Stone was published in the UK 18 years ago! I'm also very excited to confirm today that a new play called Harry Potter and the Cursed Child will be opening in London next year. It will tell a new story, which is the result of a collaboration between writer Jack Thorne, director John Tiffany and myself. I don't want to say too much more, because I don't want to spoil what I know will be a real treat for fans. However, I can say that it is not a prequel! To answer one inevitable (and reasonable!) question - 'Why isn't 'Cursed Child' a new novel?' - I am confident that when audiences see the play they will agree that it was the only proper medium for the story. I've had countless offers to extend Harry's story over the years, but Jack, John and Sonia Friedman are a dream team! It has been a huge pleasure to share with them (and soon, with you!) this untold part of Harry's story."

The Daily Mail reports that the play follows Harry Potter's parents, Lily Evans Potter and James Potter, before they were killed by Lord Voldemort, but since the author explicitly stated this story is not a Harry Potter prequel, those details may not be accurate. J.K. Rowling did not write the play herself, but she will co-produce the stage play with theater veterans Sonia Friedman and Colin Callender.
