Up until about halfway through the story, I thought this was a mildly entertaining tale. I found the idea of urban shamans interesting, and the idea of cities as sentient beings of a sort was fun to consider. By the end, though, I was hooked and very entertained.
After reading some of the criticisms posted here, I am wondering if this is a very entertaining story but one that doesn't quite hold up to a high level of scrutiny. There certainly are some questions raised here which need answering. I don't think I have answers to all of them, but here are some thoughts I had~
1] The original meeting of Toby and Gloria was too convenient and unlikely. This crossed my mind, too, but I thought perhaps the city was already drawn towards using Gloria for its plans, and somehow Toby picked up on this, and was drawn to Gloria too. So not really a random meeting at all.
2] The blizzard was a deadly event, so Gloria isn't such a hero after all. I don't know what Mur had in mind, but the only way this makes sense to me is that Charlotte used Gloria to whip up the blizzard, planning a double-whammy [keeping the city hostage physically as well as psychologically]. Gloria zapped the powerstation to avert the hostage situation [no sense in going through with the initial plan if no one could watch the hostage crisis], thus thwarting Charlotte's plan but at the same time putting others in more danger. This is certainly one of the ethical dilemmas of her power alluded to later in the story. Gloria's actions may have led to the deaths of others, but they also definitely saved the lives of some, and saved the citizens of the city from a psychological blow, and evidently led the city itself to a quick recovery [and we have already been told how deadly a sick city is to its inhabitants]. Also, by ending Charlotte's grip over her, one assumes Gloria could then essentially stop or turn the blizzard away, thus making it less severe and prolonged than it otherwise would have been, and thereby perhaps saving lives.
3] The shadowy good guy guild is unneccessary. Agreed. I wonder if Mur is leaving her options open to explore the ideas in this story, with city talkers and storm talkers etc. forming a sort of league of superfriends or union [as in Union Dues].
