Earlier this year, J.K. Rowling announced that a new Harry Potter play, Harry Potter and the Cursed Child, will debut on the West End next summer. Today, Pottermore debuted the art for the play and revealed more about its plot. And, as Rowling promised, it’s not a prequel, but a story about Harry and his youngest son—and it seems that all is not well after all.

The official synopsis, from Pottermore:

It was always difficult being Harry Potter and it isn’t much easier now that he is an overworked employee of the Ministry of Magic, a husband and father of three school-age children.

While Harry grapples with a past that refuses to stay where it belongs, his youngest son Albus must struggle with the weight of a family legacy he never wanted. As past and present fuse ominously, both father and son learn the uncomfortable truth: sometimes, darkness comes from unexpected places.

It seems like Rowling is planning a theater experience as awesome as her books: Last month, she revealed in a tweet that “Due to the epic nature of the story we’ve been working on, Harry Potter and the Cursed Child will be in two parts!” The two parts of the play are meant to be seen on the same day or on consecutive nights.
