I am a sucker for space exploration books, especially post-apocalyptic ones. Even moreso “Something is wrong with the earth and we have to go elsewhere” narratives. This book was, at its core, about a woman and her relationships to other people, particularly her family and herself. The space stuff is a bit of background scene setting but I think this worked out fairly well. Would have liked to have read more about the weird caste system and some of the pre-history to this novel, but I enjoyed this for what it is as well.
