This trod a very fine line between being a tiresome retread of old tropes (spunky girl goes to fight school to rage against misogynistic society and becomes the Chosen One Best Evar Fighter) and inverting or subverting them in unexpected ways. Not quite unexpected enough to undo the irritation of seeing those tropes played straight for a while, though. Imaginative world building. But I don't really see myself seeking out the sequel. I don't care enough.
