I appreciated how much this book fills out the world and culture of its setting through individual characters' stories, without having to do a lot of Worldbuilding per se. I found each main character in some way relatable, and particularly enjoyed the way their initially disparate stories gradually get connected to each other. In the end I didn't find it quite as satisfying as the more tightly focussed stories of the first two books, but it's very nicely done and has a lot of very timely stuff to say about ways people care for each other or fail to, and about both emigration and immigration.
