They travel to planets inserting themselves into a host body of that planet's dominant species while suppressing the host's consciousness. They access the host's memories, and occupied hosts are identifiable by silver rings in the hosts' eyes.A human on the run, Melanie Stryder, is captured and infused with a soul called "Wanderer." Wanderer is asked by Seeker to access Melanie's memories in order to discover the location of a pocket of unassimilated humans.

Wanderer begins interacting with the humans and slowly begins to gain their trust, forming a bond with Ian O'Shea.Seeker leads a search party into the desert to find Wanderer. They intercept one of the shelter's supply teams, and in the ensuing chase, Aaron and Brandt commit suicide to avoid capture. During the chase, Seeker accidentally kills another Soul, leading her superiors to call off the search.Returning to the caves, Jared and Kyle move to kill Wanderer, causing Jamie to reveal that Melanie's consciousness is alive. Jeb and Ian accept this, but...
