The Unit of Ayvy, Pol, and Nohana is now actively engaged in armed do-gooding. But Ayvy is still wanted by the interstellar authorities for murdering her pastfather and stealing some of his money. She has yet to solidify her identity in the Unit. In a huff she leaves them, and gets thrown into a castle dungeon.

Nohana and Pol have to find her, rescue her mother, deal with slave traffickers, resolve an interstellar conspiracy among the corporations to use slave labor to keep costs down and profits up, and give aid and comfort to slaves they have rescued. This enrages the corporations.

So what's a Unit to do? One thing at a time...
