The Traitor Baru Cormorant

"The Empire of Masks has devoured Baru’s home and way of life with paper currency and restrictive sexual and domestic practices, forbidding her island’s freer sexuality and family structure as unhygienic. Baru is determined to fight back — by joining the Empire as a civil servant and destroying it from within. Hiding her desire for women as deeply as her desire for vengeance, Baru navigates intrigues in far-flung Aurdwyn, first thwarting and then orchestrating regional rebellions for increasingly murky ends, while trying hard to keep her soul intact."
