I read the fourth draft and it's pretty good. I can see a bit of similarity to his Mistborn books but hey if it works it works. The story is original with a unique magic system.
I guess Vasher is the main character but you don't really get much narration from his point of view but it's pretty well done from the sisters and Lightsongs narration.
I do wish the plot was explained more. I'm left with a few questions afterwards and soon as I can i'll post it up at his website and then maybe they'll be answer in the final draft.
