I had forgotten that the epilogue of this book already contained corvids in what was basically a teaser for the next book.
I think upon second reading feels more soft-sci-fi than first, but really cool and with all kinds of things I love still.

The draw in these books for me are the "others", and they are done so credibly well! There's some tension and some solution which is less interesting than the idea of how differently intelligence might work. I love these books.
