After some hemming and hawing I've decided to make the EPUB version of the book available as an Amazon exclusive. This means that for the time being the books will only be available on Amazon in electronic format, and that if you have a KDP select membership all five books are available to read for free!
Another update to the site is up, currently for desktop/ tablet users. This update expands the details available about each individual book. There's some new concept art up on the individual book pages viewable in the slider at the top of the page. In the "books" area you'll notice a "learn more" button which will bring you to the expanded content of that book.
More concept art will be getting released over coming weeks along with some other news. In the mean time, enjoy this piece of concept art from Untold Tales:
