Best-selling author J.K Rowling announced on Thursday the seven novels in her Harry Potter series will be available as ebooks, the New York Times reports. The author also revealed future plans for the newly launched Pottermore Web site include a free interactive gaming experience based on the Harry Potter books. The site opens for registration July 31st, but will be available to all users in October.

It is my view you can't hold back progress, Rowling said. Ebooks are here and here to stay. Later than a lot of people, I for the first time downloaded ebooks and it's miraculous for travel and for children in particular. I feel great about taking Harry into this new medium.

From Professor McGonagall's past romances, to how the Dursleys met while Petunia was working in an office, Pottermore will feature new and extensive background on the Harry Potter books, the Guardian reports.

Pottermore users will have the ability to navigate through various realms within the first Harry Potter novel, Harry Potter and the Sorcerer's (Philosopher's) Stone. As users move through various chapters of the book, they will be sorted into different houses and can win points by casting spells and mixing potions.

Although Rowling has sold 450 million copies of the Harry Potter books worldwide, the author gave her clearest indication yet that she will not be writing another book for the Harry Potter series, Reuters reports.

The final Harry Potter movie Harry Potter and the Deathly Hallows: Part 2 will be released nationwide in theaters July 15th.
