I like the story thus far. A quick sweep through with a red pen would not go awry, but otherwise it seems really solid- a fantasy story with a focus on zombies in the modern world is rife with possibility. My only concern is, of course, whether the wall at Mexico's border will end up being extremely relevant or an unfortunate reference to what could have been. You took a bit of a chance with that one, but I'm fairly certain it won't be a problem.

I'll be keeping tabs and seeing where this one goes for sure.
