Attention, Harry Potter fans.

This is not a drill.

A new Harry Potter book will be published this summer.

The book, called Harry Potter and the Cursed Child,picks up the story of Harry, Ron and Hermione where the epilogue left off, according to author J.K. Rowling's website, Pottermore. The book is the script of a play by the same name opening this summer in London.

As you no doubt vividly remember, the series' final book, Harry Potter and the Deathly Hallows, closes on a scene that takes place 19 years after the Battle of Hogwarts and Voldemort's downfall.

The postscript brings the epic story full circle, depicting the beloved characters standing on Platform Nine and Three-Quarters with their families. Harry, Ginny, Ron and Hermione wave nostalgic goodbyes as their children board the Hogwarts Express and head to wizarding school.

The book ends with a reference to the series' most famous symbol: "The scar had not pained Harry for nineteen years. All was well."

From its title, the Cursed Child certainly hints that Harry's peace and parental bliss have been disrupted, but not much is known about the plot beyond the official synopsis, released in October 2015. It reads:

"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."

The script of the play opening this summer, which Pottermore bills as "officially the eighth story in Harry Potter canon," is a new tale by Rowling, playwright Jack Thorne and theater director John Tiffany.

The U.K. publisher Little Brown says the book will be released on July 31, after the play's official premiere, which is set for July 30. Scholastic will release the book at the same time in the U.S.

For a generation of readers, Wednesday's book announcement recalls feverish anticipation, endless speculation and early morning camp-outs in bookstore parking lots waiting to snag a copy of the newest Harry Potter installment.

This time around, digital editions of the Cursed Child will be published simultaneously with print copies, so parking-lot stakeouts won't be necessary. For avid fans, who — like Harry and Co. — are now adults, that's probably just fine.

It means more energy for the anticipation and speculation.
