J.K. Rowling has announced that her new stage play, "Harry Potter and the Cursed Child" will open in London's West End in 2016.

The stage play will tell the "untold part" of the wizard boy's story, including the lives of his parents who were murdered.

"Harry Potter and the Cursed Child" will run at the Palace theater in the summer of next year and tickets will become available this autumn, according to BBC.

She announced the news on her official Twitter account, on the same day that her first Harry Potter book, The Philosopher's Stone, was published in the United Kingdom 18 years ago, The Huffington Post UK reported.

Rowling revealed that the story is not a prequel, but rather an entirely new story, which resulted in the collaboration between writer Jack Thorne, director John Tiffany and herself.

"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," Rowling tweeted.

The author first announced that there will be a production of stage play back in 2013 on her official Facebook page, stating that it would be in development for the next two years.
