The Wizarding World always wanted Muggles to know about the Battle of Hogwarts, and though they tried sending subtle signs, none of them worked. They called upon an ex-Hogwarts pupil, one who was very gifted with words, to disguise herself as a Muggle and go undercover for perhaps the rest of her life. She would write the whole of Harry's story, interviewing necessary characters, and writing it down in as much detail as possible. Even if it took 7 books.
Joanne said she'd be delighted to do such a thing.
