There has been some press misreporting recently that J.K. Rowling is about to publish four more Harry Potter stories. Just to clear this up, these are not books written by J.K. Rowling.
It is a series of four short non-fiction eBooks, to be published by Pottermore Publishing, inspired by the British Library exhibition and its companion books Harry Potter: A History of Magic.
The A Journey Through… series of eBooks contains no new material by J.K. Rowling and are bite size e-reads, each themed by Hogwarts lessons, with material adapted from the companion audiobook narrated by Natalie Dormer. They have been published in this format to make the content available in other languages for the first time.
