LOS ANGELES: Harry Potter author JK Rowling is worried she will die before she finishes writing her new children’s books.

The 50-year-old is busy working on new material and revealed she has “so many ideas” to put down on paper — but she fears she won’t have the time to realise her ambitions, reports femalefirst.co.uk.

“I sometimes worry I’ll die before I’ve written them all out. That’s my midlife crisis — that I will leave this earth without having written them all,” Rowling said on a radio show.

The award-winning writer also announced plans to return to the professional name of JK Rowling, having written some of her last few works, including the crime novel The Cuckoo’s Calling, under the pseudonym of Robert Galbraith.

She said, “I have plans to write novels — in the plural — as JK Rowling again but I’m not going to give you an

absolute date because things are busy enough.

“I have an idea for a children’s book, which I really love — I’ve been writing part of a children’s book so I’m going to finish that — and I have ideas for other adult books.”
