The Traitor Baru Cormorant (The Masquerade #1) by Seth Dickinson

The Traitor Baru Cormorant is the critically-acclaimed debut novel from Seth Dickinson, one of the rising new stars in fantasy.

Tomorrow, on the beach, Baru Cormorant will look up and see red sails on the horizon.

The Empire of Masks is coming, armed with coin and ink, doctrine and compass, soap and lies. They will conquer Baru’s island, rewrite her culture, criminalize her customs, and dispose of one of her fathers. But Baru is patient. She'll swallow her hate, join the Masquerade, and claw her way high enough up the rungs of power to set her people free.

To test her loyalty, the Masquerade will send Baru to bring order to distant Aurdwynn, a snakepit of rebels, informants, and seditious dukes. But Baru is a savant in games of power, as ruthless in her tactics as she is fixated on her goals. In the calculus of her schemes, all ledgers must be balanced, and the price of liberation paid in full.
