Here is the official cover for the paperback version of The Sword to Unite. Done beautifully by an artist on 99designs, Piere d’Arterie, I highly recommend you check out some of his work.
It was a great experience to see the cover come to life the way it did. As you can see in the background, the various coat of arms can be seen on the banners behind, a really nice detail. The sword is also a great focusing piece of the cover, and exactly how I imagined it in the book.
