Rowling writes two more books

Harry Potter author J.K Rowling is already working on two more books - only days after her final Harry Potter novel became the fastest-selling book in history.

The millionaire writer has made a fortune from the hugely popular series - but she isn't ready to retire.

She said: "I'm sort of writing two things at the moment. One is for children and the other is not for children.

"The weird thing is that this is exactly the way I started writing Harry... I was writing two things simultaneously for a year before Harry took over. So one will oust the other in due course, and I'll know that's my next thing."
