I added this book to my "To Read" shelf nearly 2 years ago. I kept waiting for the implied sequel. I see a free short "prequel" is about to be released and the original book is going to be re-released. So, is the Feb 10, 2015 release different from the original Jan/Feb 2013 edition? By releasing the short prequel and re-releasing book one does that mean there is a full sequel in the near future? Thanks!
