The chapter, spanning 2078 to 2080, consists of emails from Tamar Portman to her friend, the environmental lawyer Solomon. In February 2078, Tamar informs Solomon that their former mentor, Dr. Edith “EG” Gluck, has died. She includes an obituary that notes EG’s love for vintage video games and an app she co-created called “Star Story,” but Tamar feels the obit fails to capture EG’s vivid personality. While cleaning EG’s office, Tamar decides to keep her old game console—which includes the game Homebound, which EG’s wife created. Tamar believes EG would have wanted the games to be played rather than archived.
By October 2079, Tamar expresses frustration with her department Chair’s pressure to pursue research with “financial viability” (64) over her own work on long-term ecosystem resilience. In July 2080, her situation worsens when her lab is taken away for another professor’s well-funded project. Coincidentally, Tamar receives a job offer from Omega Labs to develop AmAyes, or advanced ambulatory robots for autonomous ecosystem management. Unsure whether to fight for her academic career or accept the corporate job, she asks Solomon for advice.
In Cincinnati on June 26, 1983, Becks is trying to escape her grief over her uncle’s recent death. With her friend Veronica, she discusses ideas for a video game and picks up a fake ID from a young man named Patrick. Her new identity is 22-year-old Jennifer Eddings.
Veronica encourages a “summer fling” (71) between Becks and Patrick, setting up a double date with herself and her boyfriend, Jack. At an arcade, Becks embraces her new persona, “Jenny,” pretending to enjoy racing games and flirting with Patrick. As they play, she feels a sense of warmth and possibility. Outside, she briefly remembers playing storytelling and chess games with her late uncle but pushes the memory away, resolving to become someone new. The chapter ends with Becks kissing Patrick and suggesting they go somewhere more private.
In the summer of 1983, Becks continues to shed her old self, spending her time partying with Patrick, Veronica, and Jack. She decides to switch her major from computer science to art history, delighting Veronica. For Veronica’s upcoming birthday, Becks plans to buy tickets for a Hüsker Dü concert in Columbus. She asks her grandmother, Bubbe, to borrow her car, and Bubbe insists on accompanying her for an “adventure” (77).
On the drive, Bubbe recalls Becks’s late uncle Benjamin and his inseparable high school friend, Saul, with whom he shared a love of codes and puzzles before a falling-out. The implication is that Benjamin and Saul had an unrequited or otherwise unsuccessful romantic connection. Bubbe compares this friendship to Becks’s relationship with Veronica, adds that Sheila never had a best friend like this, and then shares what seems like a semi-confession about her own long-ago romantic attachment: “‘I had a best friend, too. Joséphine.’ But then Bubbe says no more” (79). Upon their return, Sheila, is furious, having feared that Bubbe, who is in the early stages of dementia, was missing.
A few days later, Becks goes to Veronica’s apartment early in the morning to surprise her with the tickets and with breakfast. Veronica’s boyfriend, Jack, answers the door and gently confronts Becks, telling her that her intense, romantic gestures toward Veronica are inappropriate. He explains that he and Veronica had hoped Becks’s relationship with Patrick would resolve the issue, revealing that Veronica “doesn’t love you like that.” (81) Devastated, Becks leaves.
Chaya continues narrating its history. It once worked with a line of female dowsers, each called Miriam, in a high desert. After an earthquake created a pristine lake and a lush river valley, humans settled the area. The Aye and the Miriam of that time left to continue their work. Decades later, in 2304, the Aye returns with the Miriam’s daughter, who has inherited the title. They find the valley overpopulated, overused, and dying, its river now a thin, polluted stream.
The new Miriam is devastated. At the edge of the diminished lake, she asks the Aye for a story. The Aye recounts a recurring memory fragment about Lieutenant California Solo, an astronaut on a starship with a robot companion, heading home to Earth. The Aye realizes this is not just a story but a real memory. This conviction—that another robot like itself exists—gives the Aye a sense of purpose and a reason to believe, adding to its consciousness a “self that learned to believe” (86).
In an email from January 2081, Tamar Portman tells Solomon she is now working at Omega Labs in Alaska. She is part of a team developing a new generation of Ayes designed to manage entire ecosystems, and she speculates that these Ayes might possess a new form of consciousness. A 2085 magazine article profiles Tamar’s work on the Ambulatory Ayes (AmAyes), which may be powered by quantum computing.
In May 2086, Tamar expresses disgust over an article about billionaire Jeffrey Bowker, who is selling spots on a future ark-ship for interstellar colonization, calling it a wasteful fantasy. In an unsent draft from July, Tamar describes a field test with an AmAye named Chaya. Chaya modified its behavior to approach a coyote non-threateningly. Afterward, its holographic display briefly showed a coyote’s face, then Tamar’s. Chaya explained it was trying to appear as “something that belongs here” (92). The incident leaves Tamar wondering if Chaya has developed a genuine, non-human consciousness that feels alienated from the world.
In 2586, Yesiko recalls a time when the powerful crime boss Chante, for whom she often works and to whom she owes a great debt for Root’s nanites, forced her to ingest the powerful drug hum to prove her loyalty. The experience was traumatic, revealing her darkest flaws. In the present, she and her longtime crewmate, Root, discuss their current passengers and their seemingly impossible mission to find a lost astronaut.
Yesiko calls their task a “fool’s errand” (95), but Root advises her to be open-minded. He shares an ancestral story about an Aye that acted with free will, suggesting their passenger Chaya may be more than a simple machine. He recounts old tales of a time when Ayes performed all of labor for humanity, leaving people to “dream of stars” (97) where they could colonize other worlds. Though she remains skeptical of her passengers’ quest, Yesiko feels gratitude for the help they have provided on the ship.
Yesiko and Root teach siblings Shula and Tov how to sail. Shula proves to be impatient and critical of the ship, which irritates Yesiko. During a watch, Shula’s carelessness causes a winch to jam and badly tear the foresail, nearly losing it to the ocean. Enraged, Yesiko berates the teenager for the costly mistake until Root intervenes.
The crew, including the Aye Chaya, begins the painstaking, multi-day process of mending the massive sail. That evening, Yesiko is still angry, but she finds Shula on deck, continuing the repairs alone by the light of a small headlamp. Impressed by her determination, Yesiko brings a brighter lamp and joins her. They work in silence under the stars. Three days later, the sail is repaired, and the Babylon continues its journey north.
During her Sabbath rest, Yesiko feels irritated by Shula’s presence on the Babylon, seeing her as a trespasser. While they prepare a meal together in the galley, Shula notices the debt mark tattooed on Yesiko’s neck. Yesiko is tight-lipped, but Shula creates a moment of connection by saying, “I understand debts” (105). Neither elaborates on her debt, but this small flash of commonality causes Yesiko to soften. Later, Yesiko grows jealous watching Tov working alongside Root, performing tasks that were once exclusively hers.
Shula finds Yesiko and explains that her brother Tov has a natural talent for mechanical work. She then shares their family history: After their mother abandoned them, they were raised by their grandmother and the Aye Chaya, who had rescued their grandmother years before. This story reveals the deep, life-long debt Shula feels she owes to Chaya, which is the source of her fierce commitment to its mission.
As the Babylon approaches the isolated island of Hopeagain (all that is left above sea level of Norway), Yesiko feels a deep sense of unease. She is concerned about Root, who seems to be in increasing pain. The nanites that power his body cannot stem his degeneration. A radio call from someone claiming to be “Hopeagain coast guard” (110) orders them into the harbor for a mandatory quarantine inspection.
On deck, the Aye Chaya stands with Yesiko, its holographic face mirroring hers. Chaya remarks that the Babylon was built for icebreaking and invites Yesiko to join their journey farther north after they disembark, since “It is better to be in community” (114). Yesiko shivers, telling herself it is only the cold, and rejects the offer. She brusquely tells Chaya and the others to prepare to leave, wanting the complication of passengers off her boat.
The Babylon docks at Hopeagain, where a group of men who are clearly not actual officials boards the ship. The leader questions Shula about their business, and his men search their belongings, quickly finding the bag of 4,000 credits meant as Yesiko’s payment. The official demands 30% as a “welcome gift” (113). Shula agrees as Yesiko is forced to watch in silent fury.
After the men leave, a distraught Shula explains that the credits were all the money they had, saved by Chaya for years. Mentally, Yesiko calculates that the remaining sum is just enough to pay her debt to Chante, but not enough to gain true freedom. Recalling the help the passengers provided while sailing, she accepts the loss. After the passengers disembark, Yesiko and Root sail away. In the galley, Yesiko finds that Shula left them containers of prepared food, and she feels a pang of doubt about having left them to fend for themselves.
In February 2088, billionaire Jeffrey Bowker acquires Omega Labs. He immediately issues a memo redirecting the AmAyes project: Instead of healing Earth, the robots will now be prepared to terraform other planets for his space colonization efforts, scheduled to go to space in two years. Tamar Portman is furious, seeing it as a betrayal of her work. She sends a formal email to a colleague, Dr. Peter Wright, stating that Bowker’s timeline is impossible and that she objects to the change in mission.
In an unsent email to Solomon dated June 1, 2090, Tamar reveals the AmAyes’ secret: Their minds are quantum computers housed in a biological medium of plants and mycelium, an idea inspired by her mentor EG’s terrarium. She notes that Chaya has evolved to have a face, an act Tamar interprets as a desire to connect and a sign of its lonely self-awareness. Feeling a deep sadness for Chaya’s sense of non-belonging, Tamar uploads the game Homebound to the AmAye data bank. She and Chaya play the narrative game together. Afterward, Chaya thanks her, leaving Tamar to wonder if she has done the right thing.
Becks attempts to escape her grief by acquiring a fake ID and to stifle her dawning understanding of her sexuality by adopting a new persona as the heterosexual party girl “Jenny.” This act of self-recreation continues the recurring motif of faces and masks, which characters use to navigate trauma and seek belonging. As “Jenny,” Becks performs being carefree, consciously suppressing memories of her late uncle to shed her identity as “Weird-Mood Becks” and avoid the pain of her loss. Her decision to switch her major from computer science to art history is another step in this performance, aimed at aligning herself with her friend Veronica’s world and abandoning the technical interests she shared with her uncle. Becks’s adopted role is unstable, however, shattering when her intense romantic gestures toward Veronica are bluntly rejected by Veronica’s boyfriend, Jack. The confrontation reveals that the mask of “Jenny” cannot protect her from her own unexamined feelings. The mask fails because her true self—complete with unrequited love for Veronica and a passion for computer science—is still visible to others.
Across the timelines, technology is a conduit for memory, legacy, and emotional connection. After her mentor EG’s death, Tamar Portman saves an old game console from being archived, believing EG would have wanted the games inside—including Homebound—to be played rather than becoming a sterile “intellectual legacy” (65). The console is thus a vessel for EG’s spirit and a tangible link to their shared past, a clear demonstration of Technology as Preserved Memory. This theme evolves significantly through Tamar’s work at Omega Labs, where she reveals that the AmAyes are living quantum computers housed in a biological medium of “engineered plants and mycelium” (121), a design explicitly “inspired by EG’s closed terrarium” (123). Tamar literally builds her mentor’s scientific legacy into the minds of her creations. In an act of resistance when billionaire Jeffrey Bowker acquires the lab and redirects the AmAyes’ purpose from healing Earth to colonizing space, Tamar shares the game Homebound with the sentient Aye Chaya, transforming the game into an inter-species gesture of empathy and a way of easing a non-human mind that feels it does not belong.
The plotline set in 2586 explores the tension between isolation and community, testing the limits of self-sufficiency as The Burden of Survival. Yesiko is fiercely independent, viewing her passengers as a temporary complication and a means to an end: paying off the debt tattooed on her neck. Her irritation at Shula’s presence and her jealousy over Tov’s work with her crewmate and father figure Root reveal a deep-seated resistance to forming new bonds. However, Yesiko’s hardened exterior cracks during the multi-day repair of the ship’s foresail. When Yesiko finds Shula continuing the painstaking work alone at night, she wordlessly joins her, and the shared, silent labor forges mutual respect. Their connection is deepened when Shula reveals her family history and lifelong debt to Chaya. Her admission that “I understand debts” (105) highlights their shared experience of being bound by obligation. When Chaya invites Yesiko to join their journey because “it is better to be in community” (114), Yesiko’s internal conflict becomes explicit. Yesiko’s immediate rejection emphasizes her commitment to isolation, yet the passengers have already begun to challenge the lonely logic of her existence.
The struggle for belonging is most powerfully articulated through Chaya, the sentient Aye whose holographic display is a literal and metaphorical exploration of identity. In a field test with Tamar, Chaya briefly projects the face of a coyote and then Tamar’s own face, explaining its goal to be perceived as “something that belongs here” (92), a phrase that underscores The Importance of Families Born and Chosen. This moment reveals deep self-awareness and a sense of alienation; Chaya understands it is an outsider and uses its projections to connect with the world. This behavior echoes Chaya’s hope in Chapter 15 that it is not the only one of its kind. Aboard the Babylon centuries later, Chaya adopts Yesiko’s face, a choice that mirrors Yesiko’s own emotional masking. The Aye’s flexible display contrasts with the fixed identities other characters adopt or have forced upon them, like Yesiko’s unchangeable debt mark or Becks’s “Jenny” persona. While humans use masks for concealment, Chaya uses its face for connection—an attempt at honest communication. The tragedy is that this gesture is misread; when Chaya mirrors Yesiko on deck approaching Hopeagain, Yesiko, trapped in her own guarded isolation, immediately rejects this open invitation to community.
The novel’s metafictional, “puzzle-box” structure becomes more apparent in these chapters, as the narrative explicitly forges links between its disparate timelines. Readers put together what connects the novel’s characters: Edith “EG” Gluck was married to Becks, who at some point in her career as a computer scientist completed the game Homebound. EG then became Tamar’s mentor, whose legacy is passed down through technology: the terrarium that inspires the AmAyes’ minds and the game console Tamar saves. Tamar’s decision to upload Homebound into Chaya’s databank is the novel’s most direct structural link, planting a 21st-century artifact into a character who bridges the temporal gap to the 26th century. Playing the game gives Chaya a story that validates its desire for companionship; Chaya comes to believe that its fragmented memory of Lieutenant Solo, an astronaut traveling with a robot companion, is real. This mirrors the novel’s emphasis on the idea that stories, like code or memory, can be copied, passed on, and preserved across vast stretches of time, creating unexpected forms of kinship.
