I’d give it a 3.9. Not an entirely new concept, the novella does ask interesting questions and proposes examples of how it works in this world. I didn’t have as much of an issue with the story jumping around as other did, though that may be because I was listening to the audiobook. I was a little confused as to why it was set in the 1920s rather than any other time as it didn’t really engage with the main characters being (I think it’s heavily implied) black during this time. I think it could do with a bit of finessing around the Harvey storyline but I got what it was trying to do and appreciate the depth in thought and meaning.
