YES, the proof for The Constant Tower cover just came in

Isn't this lovely? I kinda had to ask the artist to tweak it a bit though. Initially, the person in the foreground definitely looked African and was wearing African clothing. Not something Psal (my main character) does. I would've liked the tower to be shown in two ways -- one side showing the way Ephan sees it and the other side showing the way Psal sees it. But hey, you can't have everything. In this version, he gave Psal the staff, which is very important because Psal limps.

So, finally, here it is. This is just a lovely cover.
