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 sowing the seeds of civil war, Aster learns there may be a way off the ship if she's willing to fight for it.
The belowdeck slums of the HSS Matilda are full of poverty, discrimination, moral restrictions and indignities. Change can come, but only through the seeds of civil war.
