LONDON (NBC) — “Harry Potter and the Cursed Child,” the highly-anticipated continuation of J.K. Rowling’s beloved franchise, is slated to hit shelves Sunday.

The book is already breaking records.

It is the top pre-order item for both Amazon and Barnes and Noble, a spot that was last held by “Harry Potter and the Deathly Hallows.”

“Cursed Child” is a script book based on the two-part production opening July 30 in London.

The first seven Potter books have sold more than 400 million copies worldwide.
