A bit of an odd one. And unexpected from this author. Science fiction. And modified humans to the point of being alien. Doesn't quite have an ending. And almost has the feel of two novellas tacked together though both have the same pov character. The two worlds we see are quite different but we don't get deep world-building in either. Instead it is more of the fish out of water type. Some of this was a bit of a tough read. But it had intriguing questions in it that made it worthwhile in the end. Enough for me to try to hunt out what might be a related book.
