JK Rowling to write another Potter book?

JK Rowling has revealed she “could definitely” write another Harry Potter book.

Back in 2007 the writer who has had huge international success with the children’s series said the seventh novel in the series, 'Harry Potter and the Deathly Hallows', would be the last Potter book she would ever write.

However, yesterday she appeared on The Oprah Winfrey Show, telling the host that she still thinks about the book’s fictional characters often, and that she may in fact return to the tale one day.

The writer admitted that she “could definitely” write some more stories to add the series, although she was reluctant to say exactly when because she is busy working on other projects at the moment.

“I’m not going to say I won’t,” she teased.

The books have sold more than 400 million across the globe, and the films have all been blockbuster hits, making her a vast fortune and catapulting Emma, Daniel and Rupert to international fame.

The film adaptation of the last book in the series is being released in two parts, with 'Harry Potter and the Deathly Hallows Part One' due for release this November.  Check out the trailer here.
