Yoon Ha Lee’s 2020 Phoenix Extravagant is a (thus far) standalone fantasy. It’s also a mecha adventure. It’s genre-fluid.
Six years ago, the Empire of Razan invaded and conquered Hwaguk, which then became the drab Administrative Territory Fourteen, Artist Jebi is a survivor. They apply for a name change (a Razan-acceptable name) and a job as an artist for the new administration. Jebi’s sister, a Hwaguk nationalist, disapproves but hey … Jebi is a realist.
Jebi does not get the position for which they applied. They get a job offer they cannot refuse.
