Erin Zarro has written a book that I both enjoyed, and got mad at more often than not. Like a horror movie, I kept shouting at the characters for their blindness to obvious events, their credulity, and in one case, for not tying up a person that was clearly possessed, having witnessed it happen a few other times already. The characters suffer from the fun kind of stupid. If this had been a paperback copy it would have sailed across the room a few times.
But I'm glad that I took the time to read it. It's an interesting take on modern fantasy, and a world I'd like to read more into.
