Through the magic of print-on-demand technology, this "nimble" guide to the work of best-selling author J. K. Rowling provides the latest news about the author and her works, updated whenever there are significant developments. Unlike a conventional book, for which editions are printed in quantity every couple of years, this "living book" goes through frequent "mini-editions" and is printed fresh whenever customers place an order. Purchasers are entitled to free PDF updates!
