JK Rowling has finished writing a set of handwritten fairytales for charity, which were mentioned in her last book, Harry Potter and the Deathly Hallows.

There’ll be seven volumes of The Tales of Beedle the Bard, but they won’t be available to buy in stores.

One copy will be auctioned in aid of her charity, The Children’s Voice, while the rest will be given away by Rowling.
