The book featuring the script of the current hit stage production “Harry Potter and the Cursed Child” has already sold more than 3.3 million copies in North America, Scholastic announced on Wednesday.
Based on an original story by J.K. Rowling, Jack Thorne and John Tiffany, the play itself is written by Jack Thorne and is currently running in London’s West End Palace Theatre. The script book was released after midnight on July 31 — just one day after the play officially premiered — and sold more than two million copies in the first two days of its release.
