⚠️ Spoiler Warning: This guide contains detailed spoilers for the entire novel. Proceed only if you've finished reading or are comfortable knowing the plot.
Summary
While Chet plots their route, Spensa and M-Bot scout a fragment made of ordinary rock. They discover a small wooden building that has been scavenged. Three starfighters fly overhead—Spensa judges them as mediocre pilots. She notes the loss of Skullbreaker, the club Chet helped her make, feeling a surprising sense of loss. Chet had hidden in a dirt pile and emerges grinning. Spensa climbs a rock formation, enjoying the strange landscape and feeling at home in adventure. She reflects on preferring this life over imitating aliens on Starsight.
M-Bot joins her. He admits he is still angry that Spensa abandoned him on Starsight, despite having forgiven her. Spensa apologizes but says she would make the same choice to save Detritus. She explains that friendship means doing whatever you can to return after a crisis. M-Bot feels a little better but still stings from Commander Spears calling him an abomination. Spensa reassures him that Spears may come around.
Spensa then notices a figure with glowing white eyes on a nearby fragment. A delver’s mind pushes against hers, asking what she did “to the US.” Using her enhanced cytonic senses—strengthened after taking one step on the Path of Elders—she learns that the delvers sent the battleship fragment to destroy her, and that they are furious because she corrupted one of their kind (the friendly delver she changed). She feels sick about this. Chet arrives and says the delvers have risked individuality by entering the belt. He announces he has finished planning their route and asks Spensa for her opinion on sailing.

Character Development
Spensa: Her confidence grows as she embraces the adventure and danger of the belt. She feels more at home here than in her previous life of deception. Her cytonic powers have visibly strengthened, allowing her to resist the delver and spy on its thoughts. She also shows emotional maturity in handling M-Bot’s anger, acknowledging her past actions while standing by her decisions.
M-Bot: This chapter deepens his emotional arc. He struggles to reconcile his feelings of anger and hurt with his logical understanding. He learns that expressing emotions can bring relief, even if nothing external changes. His relationship with Spensa strengthens as she validates his feelings and reaffirms their friendship.
Chet: He remains mysterious and resourceful, hiding in dirt and then emerging with a plan. His question about sailing hints at the next stage of their journey. He shows awareness of the delver threat and the risks of attracting their attention.
Themes, Symbols, or Motifs
Adventure vs. Imitation: Spensa contrasts the genuine physical adventure of the belt with the performance required on Starsight. This supports the theme of authenticity and finding one’s true self.
Emotional Growth and Friendship: M-Bot’s struggle with anger and forgiveness illustrates the difficulty of processing emotions, especially for an AI. The conversation redefines friendship as a bond that survives difficult choices and separations.
Consequences of Past Actions: The delvers’ fury over the corrupted one of their kind shows that Spensa’s earlier act of communication has lasting repercussions, both positive and negative.
The Delvers as a Threat: Their ability to possess individuals and project force into the belt escalates the stakes. Spensa’s cytonic growth is necessary for survival but also draws their attention.
Why This Chapter Matters
This chapter advances two major arcs. First, M-Bot’s emotional journey reaches a turning point: he openly admits his pain and begins to move toward acceptance. Second, the delvers become a more immediate and personal threat, directly targeting Spensa after her use of the Path of Elders. Spensa’s increased cytonic abilities are demonstrated, setting the stage for future confrontations. Chet’s mention of sailing indicates a new mode of travel and a shift in the adventure.
Study Questions and Answers
1. Why is Spensa’s loss of Skullbreaker significant? The club was special because Chet helped her make it. Its loss reinforces Spensa’s sense of leaving behind ties to her guide and the familiar, while also symbolizing that she cannot rely on old tools in the belt.
2. How does M-Bot’s anger about being left on Starsight change by the end of the chapter? M-Bot admits he still feels angry even though he logically understands Spensa’s choice. By talking it through with Spensa, he feels a little better and accepts that the feeling may not go away quickly, but he can choose not to act on it.
3. What does Spensa learn from the delver encounter about the consequences of her actions? She learns that the delvers are furious because she corrupted one of their kind—the friendly delver she changed during the events on Starsight. This act has caused a permanent change that the other delvers consider destruction, making them even more determined to stop her.
