Roanhorse is killing it with this series. Also, she has an amazing sense of pace and you end up just flying through the book without noticing just how much character work is going on in the process until you get to the end and, yep, it all checks out.
As with Trail of Lightning, much of the commentary is buried pretty deep in the world building, but it’s there and searing when you see it. (Most notably the effect of the foster system on indigenous children). I stayed up late last night to finish it and since that was after a long and amazing day at a friend’s wedding, that’s saying something.
