The British author revealed in an interview with BBC Radio 2's Simon Mayo yesterday that she has another children's book in the works. "I have so many ideas. I have written part of a children's book that I really love, so there will be another children's book," she told Mayo, noting that the "absolute date" has yet to be determined. Rowling also mentioned that she's brimming with ideas for some new adult books. "I sometimes worry I'll die before I've written them all out," she said. "That's my mid-life crisis." Let's hope that doesn't happen! By AMNY.COM Share on Facebook Share on Twitter Comments Comments section is temporarily on hold. Here’s why.
