My author friend needed another book cover. The last one I did was a short story inbetween Book 2 and 3. This would be book 3. It's much more simple than the last one, but it follows what his old Book1 and Book 2 covers were, which was:
-Book 1: A leatherbound book covered in runes
-Book 2: Those runes burning away, showing that stone is underneath the leather.
-Book 3: The new set of runes revealed on the stone.
