Countess - Suzan Palumbo

A queer, Caribbean, anti-colonial sci-fi novella in which a betrayed captain seeks revenge on the interplanetary empire that subjugated her people for generations
Virika Sameroo lives in colonized space under the Æcerbot Empire, much like her ancestors before her in the British West Indies. After years of working hard to rise through the ranks of the empire's merchant marine, she's finally become first lieutenant on an interstellar cargo vessel.
When her captain dies under suspicious circumstances, Virika is arrested for murder and charged with treason despite her lifelong loyalty to the empire. Her conviction and subsequent imprisonment set her on a path of revenge, determined to take down the evil empire that wronged her, all while the fate of her people hangs in the balance.
