I really enjoyed this book. Lots of rich history and culture, and ways to integrate that into a character. It really makes me want to explore the Mwangi Expanse or the River Kingdoms, or even Old Cheliax. I just have one problem with it: It was basically all about humans.
That's fine when it's the idea of a book. Humans deserve just as much of a spotlight as any other ancestry. But when this was supposed to be about the rich diversity of Golarion, 99% of it was about the diversity of one specific inhabitant species. Alkenstar, a single city-state in a desolate wasteland, got as much attention as the entire nation of Kyonin, and several times more than the three Mualijae nations put together - and that's just the Elves.
Again, I still loved the book, and I'm keeping it around for inspiration. I just think a better title for it would've been "Humans of Golarion."
