I simply could not finish this book. It's a hot mess with too many ideas crammed into too small an area. A city built in the body of a long-dead giant: okay. Superheroes fighting the tyrant rulers of a once-noble Republic: sure. Spark-storms that come unpredictably and randomly mutate ordinary citizens into monsters or heroes: that works. Put them all together and add in a few dashes of steampunk tech (as best I can tell mixed in with strong-AI-level robotics), a weird and nonsensical mix of races (each of which has one, and only one, super power and set of unique physical characteristics), and it just becomes too much. There's never time to really flesh out any single facet of the story, so it just rushes by forgettably.
