Harry Potter and the Cursed Child is set to on Harry Potter’s birthday on July 30. But today, J.K Rowling announced that the script of the play will in fact be released as a two-part book, at 12:01 a.m. on July 31, 2016.

Pottermore is proud to be a key part of the multi-platform effort that will allow the epic eighth Harry Potter story to be read and enjoyed by a wider, global audience

said Susan L. Jurevics, CEO of J.K. Rowling’s online home base Pottermore in an announcement on the site.

Though, the play was not written by JK Rowling herself, but by English playwright Jack Thorne who wrote the script based on an original new story she wrote with Thorne and theater director John Tiffany, but never released as a book.

It is set 19 years after the end of Harry Potter and the Deathly Hallows, the series’ final book; where Harry is an overworked employee of the Ministry of Magic, a husband, and father of three school-age children. In the epilogue to Deathly Hallows, readers learned that Harry had married Ginny Weasley and together they had two sons, Albus and Severus, and a daughter, Lily.

In Harry Potter and the Cursed Child, Albus struggles with the weight of a family legacy he never wanted, the announcement said:

As past and present fuse ominously, both father and son learn the uncomfortable truth: sometimes darkness comes from unexpected places.

The play and book will not be the only Potter-related releases this year. Fantastic Beasts and Where to Find Them, a movie based on one of Rowling’s short Harry Potter companion books, hits theaters Nov. 18.
