Ibari Waker is an agent for Service, the secret police of an authoritarian state. She works under the cover of an urban planning professor in the town of Fillmore, a role she takes seriously. Years into this post, she accidentally breaks her glasses and repairs them with silver tape, soon discovering that the tape foils the State’s ubiquitous facial recognition technology. When she mentions this to her friend Nico Li, Nico gives a barely perceptible warning shake of her head, which Ibari interprets as confirmation that Nico is also a Service agent. Restless with her quiet life, Ibari applies for a promotion to detective.
Eight years later, Ibari is a detective in Los Angeles, but travels to Ohio after her parents’ death to deal with their estate. Nico, a physicist at UCLA, secretly visits Ibari in Ohio. Nico explains she is involved in a dangerous experiment intended to help dissidents escape the State via teleportation and makes Ibari promise to protect her two young children, Samir and Marlowe, if she something goes wrong. A short time later, Ibari’s superior at Service, Alberto Vasquez, informs her that Nico and another scientist vanished during an illegal quantum entanglement experiment, while Nico’s husband, Kareem Fayed, was somehow duplicated.
Ibari interrogates Nico’s husband, whom she refers to as Fayed to distinguish him from his doppelgänger. Fayed denies involvement with the Resistance and insists his experiments were designed to benefit the State. He recounts how Nico and Saraya attempted to teleport to the other side of the room but disappeared. When Fayed attempted it himself, he made it to the other side of the room, but reappeared next to an identical double of himself. Next, Ibari interviews the second Kareem, who explains he is from a parallel reality where the United States fragmented after civil war and a coup d’état. He reveals that a woman matching Nico’s description—a woman identical to his friend, Gloria, except for Gloria’s distinctive scar— appeared at a party in his world. He tells her Gloria was pregnant with his child, which made him feel so happy. He says, “I was so excited to be a father […] I'd been reading everything I could about it," he said, "since she told me. Parenting blogs, books, everything” (236). He tells Ibari that her own doppelgänger also attended his party, a woman named Ari who had served 18 years in prison for taking out a contract on her cousin, Anton Waker, though whether the charge was murder or attempted murder he doesn’t know. Ibari is shocked by this connection since her own cousin, Anton Waker, is like a brother to her.
A year passes. Ibari visits Fayed, who has poured himself into his work and neglected his children. Ibari concocts a plan. While investigating a counterfeit exit visa case, she prompts her informant, a hairstylist named Latika, to name a Service colleague of Ibari’s named David Grissom as corrupt. Ibari uses the recording of her interview with Latika as leverage over Grissom, making him corroborate her cover story for a visit to the camp where Kareem is being held in exchange for making the accusation go away. At the camp, she slides Kareem her broken glasses with the silver tape on them to make his face unreadable to facial recognition. Telling the staff he is Grissom, Ibari breaks him out without being detected. As they escape, she makes a holographic recording of his testimony about the other world.
Ibari takes Kareem to Nico’s house where Fayed has packed his things and is preparing to leave. When she asks him if he was happy about becoming a father in Los Angeles, Kareem says, “I liked the idea of just, of having more in my life, I guess. Being of service to someone, being there for a kid who needed me. Helping to take care of a person" (269). Ibari asks Kareem if he is willing to raise Nico’s children, Samir and Marlowe, who are three and five years old, as his own so Fayed can leave to lead the Resistance. Kareem agrees and immediately begins to turn Nico’s house into a home for Samir and Marlowe. They quickly begin to call him Dad, and over time they forget they ever had another father.
Thirty years later, a 79-year-old Ibari resigns from Service and orchestrates a massive leak of State secrets. She travels to a shantytown in the “burn zone,” where the Resistance is headquartered. She meets with Fayed, who now lives there as a “ghost”—a person without official status. She tells him that Kareem is dead and provides him with a phone containing all the data she downloaded from Service—enough to bring down the surveillance regime and allow the Resistance to rise. As they’re talking, Marlowe arrives looking for Fayed. Ibari leaves, making Fayed promise to show Marlowe the recording of Kareem’s interview on her phone so she will know the truth about the parallel world and what happened to her mother. Ibari walks to a nearby beach, looking out at the ocean as Service agents close in to arrest her. After watching the recording, Marlowe is questioned by State agents but successfully lies about what she has seen and done.
Ibari Waker’s reflection on her dual identity as a Service agent and a college professor reveals the psychological split required to live under constant surveillance. She insists that her cover wasn’t a lie, noting, “it was actually true that I was a junior professor in an urban planning department” (200). By investing genuine effort and finding satisfaction in her public-facing role, Ibari embodies the coping mechanism necessary to survive in a society where one’s true self must be perpetually concealed. This personal bifurcation mirrors the state’s foundational principle, where Surveillance as the Price for Harmony demands a constant, exhausting performance of compliance. Reality, as Ibari observes, “splits into two” (200), forcing citizens to navigate the chasm between their private thoughts and their state-sanctioned identity. This internal division, which Ibari initially sees as an “expansiveness” (201), eventually becomes an unbearable “splinter” (204) that fuels her desire for a more authentic, unified existence, leading to her later rebellion.
The accidental creation of Ibari’s foil-repaired glasses introduces them as a symbol of resistance that critiques the idea of surveillance as the price for harmony. What begins as a mundane accident—stepping on her glasses in the backyard—becomes the catalyst for Ibari’s ideological awakening. The silver tape inadvertently creates a tool that defeats the state’s facial recognition technology, exposing a “flaw in the world” (209) and suggesting that the regime’s technological control is not as absolute as it seems. This discovery allows Ibari to access forbidden spaces and experience a thrilling sense of anonymity, leading her to a surprising revelation: “The surprise wasn’t that chaos had always been there, embedded just under the surface. The surprise was that I liked it” (207). The glasses symbolize a crack in the monolithic authority of the State, demonstrating that vulnerabilities exist within even the most oppressive systems. Ibari’s later decision to give the glasses to Kareem to enable his escape from the detention camp transforms the glasses from a symbol of minor subversion into a key device that unlocks Kareem’s freedom, cementing Ibari’s transition from passive observer to active dissident.
Kareem’s arrival from a parallel reality during Fayed’s teleportation experiment, underscores the novel’s thematic exploration of The Hope of Multiple Possible Futures. This alternate Kareem describes a world where the United States did not consolidate into a single authoritarian State but instead fractured into warring factions after a civil war. This revelation reframes Ibari’s reality as one of many contingent outcomes. The concept is made more personal when Kareem tells Ibari about her doppelgänger, Ari, a convicted criminal who served 18 years for taking out a contract on her cousin. This knowledge destabilizes Ibari’s sense of a fixed identity, forcing her to confront the idea that her life as a loyal agent is the product of circumstance rather than innate character. The existence of another self who made radically different choices suggests that rebellion and criminality are both possibilities latent within her, a realization that empowers her eventual break from the system.
Nico’s clandestine visit to Ohio provides the emotional impetus that transforms Ibari’s abstract restlessness into a concrete mission. By disabling their surveillance watches and speaking candidly about her subversive experiment, Nico performs a radical act of trust that solidifies their bond beyond their shared, secret Service identities. Her desperate plea for Ibari to protect her children if she disappears—“I don’t want my children to grow up in a surveillance state” (219)—shifts the novel’s central conflict from an ideological struggle to a personal one. Ibari’s promise to her friend becomes a moral imperative that overrides her duty to the State and changing the course of her life. This commitment is driven by human loyalty, love, and a desire to protect the innocent from the regime’s dehumanizing reach. This vow becomes the guiding force behind all of Ibari’s subsequent transgressive actions, from engineering Kareem’s escape to orchestrating the massive data leak 30 years later.
Amid the disorienting revelations of quantum entanglement and parallel worlds, the painting Swan Dive emerges as a tangible object that grounds the narrative and connects its disparate threads, emphasizing The Connective Power of Art. Mentioned by Fayed during his interrogation, the painting is what he grabs to test the teleportation technology after Nico vanishes—a human, artistic object thrust into a moment of scientific horror. Ibari later inherits the painting, creating a physical link to Nico’s memory and the mysterious experiment that tore her from their world. The artwork becomes a touchstone, a piece of shared history and beauty that endures even as people, and entire realities, slip away. Its presence in the story, which connects to the broader literary multiverse established in Mandel’s other novels, reinforces the idea that art can provide continuity and meaning that transcend political borders and the boundaries between people.
