Film Trailer: 'Fantastic Beasts and Where to Find Them'

J.K. Rowling is the top dog again.

'Harry Potter and the Cursed Child , Parts I & II,' the eighth story in the Harry Potter series and the first official Harry Potter story to go to the stage, is leading the Amazon best sellers list this month so far -- and it isn't even available yet. The book revolves around Harry Potter's life 18 years later as a Ministry of Magic employee and the weight his son, Albus, feels as the child of a legendary wizard.

The book's success shouldn't come as a huge surprise since Potter-mania has once-again reached a fever pitch with the new installment of the Wizarding World of Harry Potter opening at Universal Studio's in Hollywood and Rowling's latest creation, "Fantastic Beasts and Where to Find Them" hitting theaters in November 2016.

The book, which is already available for pre-order in hard cover and paperback, will hit shelves is will premiere on stage at London's West End on July 30.

You can pre-order the book now!
