Well written. I found it somewhat dour, coming to it after Tamsyn Muir and Helen Harper. The plot is closely worked, and the interweaving voices work quite well.
The central voices here are of black people, a father and his daughter. Many writers of fantasy these days throw minority voices into their mix, but in a way that just seems to be window-dressing : skin colour as just another empty bit of character building. Harrow here acknowledges the realities of racism and weaves them into her story in way that makes sense.
