In an interview with BBC radio, Rowling said that she had written part of a children's book that she really loved, E!Online reports.
However, Rowling did not reveal the topic of the new book nor whether it would be something like 'Harry Potter'.
The 50-years-old novelist said that she also had ideas for adult books, adding 'I sometimes worry I'll die before I've written them all out. That's my mid-life crisis.'
