clients—also wants to hire "Security Consultant Rin". Murderbot is content to know that it has options. "The Future of Work: Compulsory" SecUnit deals with callous humans in an engagement previous to meeting the Preservation team. "Obsolescence" On an education space station near Jupiter, an augmented human named Greggy is found dead. Station manager Jixy investigates and finds Greggy has been brutally murdered and several augments from his body have been stolen by the killer. This story provides clues about the origins of SecUnits and the Corporate Rim society. Network Effect Murderbot has been sent by Dr. Mensah on a research expedition that includes her daughter Amena, her brother-in-law Thiago, and Drs. Arada, Overse, and Ratthi. Their ship is set upon by a hostile transport vessel, which Murderbot and Amena are compelled to board as the others flee in an escape pod. As the transport moves into a nearby wormhole, Murderbot hunts the grey-skinned humanoids in control of the ship, isolates Amena and the human captives Ras and Eletra in a safe zone, and begins to realize that the transport is the same one once controlled by its robot pilot friend ART. Arada and the others, who have followed the ship into the wormhole, are able to board as Murderbot finishes off the hostiles and manages to reload a deleted ART with a code phrase left for it.

The missing crew have effected their own escape, and while Arada and her people help them, Murderbot is captured. ART begins firing missiles at the colony, demanding its release. Murderbot is rescued with the help of another SecUnit whose governor module it disabled, as well
