I absolutely adored this book.  I realise that part of this is that it was a perfect little escape while I was stuck at home with covid, but I do also think it's really wonderful.
It has some similar strengths to the first in the series, in that it's mostly about the relationships between a few outcast characters that become a chosen family and just happen to be in space.  But if anything I think it's better written (I guess Chambers getting into her stride with book 2), and benefits from being a more focussed story of a smaller number of characters.  And has some weightier things to say about embodiment, the tension between fitting in and freedom, and loyalty & reciprocity.
I am excited about the rest of the series.
