Quite the beaut, eh? If you didn't check out the evolution of a book cover blogpost on ATB, you really should. It's a fun time.
You know what? I was about to write a brief synopsis, but you know what I think would be more interesting? Why don't you tell me in the comments what you think the plot is, based on the cover alone? (No fair cheating if I've already told you what it's about.) I'd be interested to see if it conveys as much of the plot as I think it does. Should be a fun experiment anyway. So fire away!
