This is a very cathartic book in which the heroine goes magnificently all-in on a revenge that grows from the initial single person target to patriarchy itself. It does suffer a bit from the YA tensions getting resolved too quickly/tidily syndrome, and I found its setup a little too video gameish, but I'll probably still read the sequel.

At first I was very annoyed with the simplification of qi into categories and a precisely measurable "spirit pressure", but I can see how doing that sidestepped having to do a hundred pages of worldbuilding before anything much happens.
