Rowling says she’s considered another Potter novel
Author J.K. Rowling says she has considered writing another Harry Potter novel, although fans may have to wait another 10 years.
The bestselling author of the teen wizard series has hinted in an interview with Time magazine that she has had “weak moments” in which she’s thought of writing an eighth book.
“If ó and it’s a big if ó I ever write an eighth book, I doubt that Harry would be the central character. I feel I’ve already told his story,” she said.
“But these are big ifs. Let’s give it 10 years.”
The seventh instalment of the wizard-in-training books ó Harry Potter and the Deathly Hallows ó came out in July. It instantly became the fastest-selling book of all time, with more than 15 million copies purchased within 24 hours.
Rowling’s six previous Harry Potter books sold more than 325 million worldwide.
Rowling, who Time positioned at No. 3 in its Person of the Year list, is thought to be working on an adult novel.
The 41-year-old writer hit the headlines in October after revealing that one of Harry Potter’s main characters, Albus Dumbledore, is gay.
She told an audience of fans in New York City that as a young man, Dumbledore had fallen in love with Gellert Grindelwald, who later became a rival.
Rowling said her novels are really a “prolonged argument for tolerance.”
The film version of Harry Potter and the Half-Blood Prince, the sixth book in the series, is due for release late next year.
