Opening up the wider world and bringing in politics between the cities was the only mildly interesting part. The biggest problem is Tally is a terrible character. Supposedly a strong driving force but mostly just sways with (or perhaps against) whatever prevailing wind is blowing. I probably won't bother with #4.
