Rem T. Saikle is a struggling man on his planet, Melatai, who faces classism alongside his older sister, Piper.
However, when Trauvia, a planet-turned-mothership, arrives and announces its plan to eradicate Melatai after enslaving hard-working farmers and fishers, Rem is forced to defend himself and his people, using a sword he stole from the Trauvians.
And after Leader Seax, Trauvia's supreme leader, notifies Rem of the kidnapping and ransom of his sister, Rem must do something only the insane would do: Stop the entire army.
