[books] Talk to me about Ninefox Gambit?

I have just finished it, rather late to the party (I was stuck, for several months, partway through Kalpa Imperial, which I found rather a slog, and suspect I didn't understand). I have a lot of inchoate thoughts about the ethics/mechanics/pragmatics of the ending, which I would like to sort of flap at people about, and in general I enjoyed it a lot and am really looking forward to subsequent books.

Links to discussion posts I avoided around release due to Spoilers v welcome.

(The author, Yoon Ha Lee, is on DW as yhlee and I greatly enjoy reading the short fiction including crackfic AUs of this series that he posts, along with everything else.)
