Extremely well written, very engrossing, but ultimately the whole reason behind (view spoiler)[the zombies curing themselves (hide spoiler)] made absolutely no sense and was thin, rushed, and frankly really weird and illogical (if logic can be expected in a book about zombies). As I got closer and closer to the ending, I kept waiting for an explanation to the most miraculous part of the story, and it never came. Marion is writing fiction, FANTASY. I think he could have put a bit more effort into making the most original part of his story stronger.
