Chambers closes out her space opera trilogy by returning back home to the humans who, despite making contact, despite having arrived, despite having been (reluctantly) accepted into a multi-species society where they remain the poor country bumpkin refugees, still cling to their generation ships and old traditions. A paean to community, to identity, to long-term thinking and reinvention... yeah, it gets very idealistic, perhaps overly so, and uses a bare-bones plot and far too many narrators to get there. But somehow it feels right that a series as optimistic as Wayfarers ends with a book that's so far into optimism, as a dream of survival against impossible odds, that it feels like a hippy dream. Right now, that's not necessarily a bad thing.
