Harry Potter’s next adventure will be in the cloud. Google officials and author J.K. Rowling announced today that when Rowling’s new Web site Pottermore.com goes live in October, U.S. visitors will be able to store their Harry Potter e-books in their Google Books libraries.

As previously announced, Pottermore will be the exclusive place to buy Harry Potter e-books and digital audiobooks. But now, users will be able to buy those e-book editions from the Pottermore Shop, push them to their Google Books library, store them alongside other Google eBooks, and access them in the cloud (alongside their other Google eBooks) on virtually any device with a modern browser.

In addition, the agreement names Google Checkout “the preferred third party payment platform” for all purchases made on Pottermore.com.
