LONDON (AP) — Good news, Harry Potter fans: J.K. Rowling says she is working on a new children's book. There could be a bit of a wait for it, though.

The boy wizard's creator told the BBC that she has not abandoned children's fiction, even though she is now busy writing detective novels under the pen name Robert Galbraith and working on a screenplay for the film adaptation of her book "Fantastic Beasts and Where to Find Them."

She said "I've written part of a children's book, which I really love. I will definitely finish that."

Rowling's literary agent, Neil Blair, said Wednesday that work on her children's the book "is ongoing, with no plans to publish as yet."
