Cursed Child of series already a US best-seller

Harry Potter is casting a spell, again, over the publishing industry.

Nine years after the publication of the seventh and last book in the best-selling boy wizard series, pre-orders for the script of a new, sold-out London play is the most pre-ordered book since 2007 in the United States, retail book sellers Barnes & Noble said on Monday.

Harry Potter and the Cursed Child is billed as the eighth story in the series and is to be published at midnight on Sunday. A script rather than a narrative novel, it is being published a day after the official opening of the London stage production of the same name.
