Ok read chapter 5...
A nice change of pace, spending the whole chapter on the conflict is a good idea, gives it the attention it needs.
It felt weird at first to me because the genre changes suddenly here, from a fantasy/war type thing to a horror/zombie feel. It kind of threw me off at first because I wasn't expecting it, but I guess that was on purpose.
Just got a few short comments:
There's a line that says "Looking down upon her Harper could see the eyes staring up into the sky, full bodied blackness as deep as the night sky reflecting his gaze with a swallowing emptiness." - I think the word sky is used too much, maybe drop one of them somehow.
Likewise there's a line that says "The street gave way to a rude square perhaps fifty feet across with perhaps four main avenues clearly visible." - I think "perhaps" is used too much. Either drop one of them or both of them. Because this is written in "god-like" POV, it makes the narrator seem uncertain about things, when I think what you're really tring to get across is that the
character is uncertain about things. I don't think the narrator should ever be uncertain, because he knows everything that is going on in the scene.
EDIT - just had a bit of a re-read of this section actually, and it seems to me now that it's Harper's POV, not the god POV. So maybe the above comment doesn't really matter

Don't know why I had it lingering in my head that it was the god POV.
One last thing... the section at the top of page 36 needs breaking into more paragraphs! It's a huge section written in only one paragraph. It's possible I missed some breaks, but I find it hard to tell, because you son't use tabs (btw, use tabs!

).
That's it for now...
