I love this series, because Becky Chambers writes in a sci-fi universe with heart, which is to say that the science-fiction is the background, while the characters have primary importance. In this, we see what the Exodus Fleet that was mentioned in Book 1, and in passing in Book 2, in greater detail. We understand more what human refugees from Earth left, and what they preserved. We get to see what life is like among the stars.

When I first started reading this, I thought The Long Way to a Small Angry Planet was what it means to be a family, even if not by relation, and A Closed and Common Orbit was about what it means to be human.

But I think that's wrong. I think Book 1 is about the importance of family. I think Book 2 is about the importance of the individual, and what it means to be a person. And Book 3 is the exploration of the importance of society. They're sneaky-smart books. They're fun books. They're books I will read again.
