Harry Potter is coming to the stage in 2016.

Details have emerged about a forthcoming play, Harry Potter and the Cursed Child, which will make make its debut at the Palace Theatre on London’s West End next year.

Potter author J.K. Rowling collaborated with English television writer Jack Thorne and director John Tiffany (a Tony winner for Broadway’s Once) on the project, which Rowling said on Twitter was not a prequel. (Thorne and Tiffany recently teamed up for Let the Right One In, the well-received stage adaptation of the 2008 Swedish horror film.)

“It will tell a new story,” Rowling wrote, but declined to provide more details. “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.”

News of the Potter stage adaptation first broke back in December 2013, when Rowling announced she was developing the project about the early days of Harry Potter before he attended Hogwarts. The official statement at the time declared that the play would “explore the previously untold story of Harry’s early years as an orphan and outcast” with appearances from familiar book characters.

A new report from The Daily Mail claimedCursed Child would also offer a look into the lives of Harry’s parents, Lily and James Potter, before they were (spoiler alert, depending on whether you’re awful) killed by Lord Voldemort. (A helpful timeline refresher: Harry was born on July 31, 1980; Lily and James were killed on Oct. 31, 1981; and Harry lived with the Dursleys until entering Hogwarts in September 1991.)

Rowling did not write the Cursed Child script; she is co-producing the venture along with veteran theater producers Sonia Friedman and Colin Callender. On Twitter, she explained why Cursed Child did not become a new Potter novel.

“To answer one inevitable (and reasonable!) question — why isn’t #CursedChild 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,” she wrote.

This post has been updated to include statements from J.K. Rowling. An earlier version of this piece called the play a “prequel.”
