The Harry Potter author made the exciting announcement on X after being asked if she would consider writing a space odyssey. "The one I'm planning to finish first is futuristic, but not a space odyssey, sorry. Definitely earthbound.” Since finishing the Harry Potter series, Rowling has kept busy by releasing books including The Casual Vacancy and The Strike Series. The 59-year-old author has so far released seven Strike crime novels, under the pseudonym Robert Galbraith and fans are eagerly awaiting the eighth instalment The Hallmarked Man.
