Odd-mannered, obsessive, withdrawn, Aster has little to offer folks in the way of rebuttal when they call her ogre and freak. She's used to the names; she only wishes there was more truth to them. If she were truly a monster, as they accuse, she'd be powerful enough to tear down the walls around her until nothing remained of her world, save for stories told around the cookfire.Aster lives in the low-deck slums of the HSS Matilda, a space vessel organized much like the antebellum South. For generations, the Matilda has ferried the last of humanity to a mythical Promised Land. On its way, the ship's leaders have imposed harsh moral restrictions and deep indignities on dark-skinned sharecroppers like Aster, who they consider to be less than human.When the autopsy of Matilda's sovereign reveals a surprising link between his death and her mother's suicide some quarter-century before, Aster retraces her mother's footsteps. Embroiled in a grudge with a brutal overseer and sewing the seeds of civil war, Aster learns there may be a way off the ship if she's willing to fight for it.
