JKR in USA Today
In an interview with USA Today, JK Rowling addresses life after Harry Potter, as well as her reaction to the numerous Deathly Hallows spoilers, which leaked only days before its release:
“I had been working toward that point [the epilogue] for a long time. I did have a sense-of-humor failure when the epilogue went up.”
As always, proceed with caution if you have not yet finished the book, as this article contains SPOILERS.
