The last two novellas were much harder to follow and took the focus away from the twins completely. Mokoya wasn’t even named in the fourth novella. I’m all about multiple narrators and perspectives, but I wish it had brought us back to Mokoya and Akeha in the end. We didn’t even get to hear about Akeha transitioning to they/them pronouns from their own perspective. They were reluctant to pick a gender in the first novella so it was cool to see that come full circle with them deciding the didn’t have to choose between man and woman, but why do we hear about this from a third party observer? Some of the world building was also a little confusing, like why does the sun set multiple times during the day? This was a specific detail that wasn’t fully explained so it didn’t really add anything to the story. All this to say, I’d rate the first two around 3 or 4, the second two around 2 or 3.
