Part 1: A-SIDE
Chapter 1: Homeland
In the spring of 2031, Ari Waker lives in Echo Park, Los Angeles, with her traumatized roommate Gloria after completing an eighteen-year federal prison sentence for contracting a hit on her cousin.
Gloria convinces Ari to attend a party hosted by Kareem Fayed in Silver Lake to celebrate the lifting of the municipal curfew.
At the crowded party, bizarre anomalies occur: a woman named Saraya appears in two different outfits simultaneously, and a woman identical to Gloria but without her forehead scar calls herself Nico and identifies Ari by her legal name, “Ibari”.
Ari notices the painting Swan Dive by L. Alkaitis and witnesses Kareem behaving erratically before he completely disappears from his own apartment.
Over the next six years, Ari drifts through jobs across Las Vegas and Deseret before settling in the Ohio Republic. There, she meets Felix, an ex-ballet dancer turned illegal arms dealer, and begins working for Eduardo Harris, a private investigator.
Eduardo hires Ari to surveil a client’s wife named Nico, whom Ari realizes is actually her former roommate Gloria living under an assumed identity.
When Ari contacts James, he reveals that “extra people” or doppelgƤngers appeared at the party, suggesting the gathering functioned as a swinging door between parallel dimensions.
After learning from Nico that Saraya was committed to an LA psych ward, Ari and Felix are forced to flee Texas after receiving a warning note reading “RUN”.
Chapter 2: Paris
Years later in Paris, an elderly, disabled Ari Sorianoāwho walks with a cane after surviving a fatal boat explosionāis visited by a young student named Sebastian Li.
Sebastian pretends to discuss art history, but his true motive is to steal Ari’s prized painting, Swan Dive.
Ari reflects on her past: after fleeing Texas with Felix, they escaped to Vancouver, Paris, and Greece, where Felix was murdered at a cliffside diving platform after blabbing about their gunrunning to mercenaries.
Following Felix’s death, Ari married Bill Soriano, an operative who illegally transported people out of organized crime, but Bill died when their boat was blown up on the Seine by anti-dome extremists, leaving Ari severely injured.
Realizing Sebastian has stolen Swan Dive, Ari pursues him into the rainy streets of Vincennes. In an alleyway, a mugger violently assaults Ari, snatching her handbag and causing her head to slam against the pavement.
Sebastian finds her bleeding and severely concussed; though he tries to take her to a hospital, Ari refuses and demands to stay with her painting.
Sebastian carries her to the minimalist apartment of his guardian, Nico, and lays Ari on a bed with Swan Dive propped up before her. As her consciousness fades, Ari hallucinates the presence of her late third spouse, the pianist Eddie Kalisa, coming to guide her into death.
Chapter 3: Three Conversations After an Explosion
This chapter consists of three recorded hospital transcripts between Nico Li and Ari Soriano in Paris during the fall of 2039, following the Seine boat explosion.
In the first conversation, Ari details her upbringing surrounded by stolen antique dealers, her post-9/11 business selling fake US passports, and her conviction for paying a hitman to eliminate her cousin Anton.
Ari admits that although Anton survived, she knows another innocent man was mistakenly killed in Italy. In the second conversation, Nico reveals that she was a quantum physicist in a parallel reality called “The State”.
During a 2031 teleportation experiment at UCLA, Nico was unexpectedly “plucked like a guitar string” and materialized in Kareem’s kitchen in Los Angeles, leaving behind her husband and two small children, Marlowe and Samir.
Nico describes finding her colleague Saraya in an LA psych ward, wandering through DP camps, meeting Ari in Ohio, and eventually moving to Paris to track down Gloria.
In the brief third conversation, Ari refuses to trust Nico or depend on anyone, asserting that self-reliance has been her life’s sole rule.
Chapter 4: The Birthday Present
Sebastian Li recounts his adolescence in Normandy and Paris, driven by an obsession with Ari Soriano and a desire to reclaim Swan Dive, the painting his biological mother Gloria sold to Ari.
Sebastian was primarily raised by Nico, who acted as a devoted mother figure while Gloria remained emotionally detached and traumatized by her past.
Over several years, Sebastian researches Ari’s criminal history, befriends her pianist wife Eddie Kalisa before Eddie’s sudden death, and plans the art heist with his school friends. At age twenty, Sebastian successfully steals Swan Dive from Ari’s apartment and flees to Gloria’s home.
When Ari tracks him down, she is mugged in the street; a panicked Sebastian brings the concussed woman back to Nico’s apartment, where she dies in the guest bedroom.
When Nico arrives home on her birthday, Sebastian presents Swan Dive to her as a gift, claiming he bought it back, which deeply moves her.
Discovering Ari’s corpse in the adjacent room, Sebastian realizes he must protect Nico from police involvement and contacts his friend Obie to make Ari’s body disappear, entangling himself in local organized crime.
Chapter 5: Paris
In a brief, poetic stream of consciousness from the back room of Nico’s apartment, Ari experiences her final moments of life. Looking at Swan Dive propped on the dresser, she reflects on her lifelong impulse toward extremity, destruction, and self-reinvention.
She expresses deep regret over her past crimes, wishing she could rewind time to prevent the hit on her cousin Anton or alter the events at Kareem’s party.
The ghost of her late spouse, Eddie Kalisa, enters the room and warmly invites Ari to join her. The physical boundaries of the room dissolve into the oil-painted waters of Swan Dive.
Ari takes Eddie’s hand, steps onto an imaginary diving board, and dives into the ocean as her life ends.
Part 2: B-SIDE
Chapter 1: Transport
In the authoritarian “State” of an alternate timeline, thirty-four-year-old transport professor Marlowe Li endures a psychologically abusive marriage with her husband Hugo. During a tense late-night car ride beneath ubiquitous State surveillance cameras, Hugo berates Marlowe, prompting a sudden realization that pushes her to file for divorce.
Eighteen months later, while delivering a holographic lecture on transport theory, Marlowe receives frantic text messages from her brother Samir informing her that their father, Kareem, is dying of cancer. Samir, an architect working on the moon, abandons a high-stakes client meeting to fly back to Earth.
Marlowe travels to Los Angeles to their childhood home, where Kareem lies dying despite universal infant cancer immunizations. Before passing, Kareem cryptically tells Marlowe that he saw her mother Nico “afterward” and that Detective Ibari Waker “made it possible”.
That night in the garden, Samir witnesses an intruder sneaking through Kareem’s windowāa man who looks and sounds identical to their father.
Samir chases the man into an alley, where the stranger claims his name is Kareem Fayed and asserts “there is no state behind the State”.
When Samir texts Detective Waker asking about the double, she replies that he is “A ghost,” before she resigns from the Internal Security Service by incinerating her devices.
Chapter 2: True Diligence
Detective Ibari Waker reflects on her lifelong career in the Internal Security Service, guided by the childhood motto “True diligence is following the improbable path”.
In 2031, when the UCLA teleportation experiment malfunctioned, Nico Li and Saraya vanished, but two genetically identical Kareem Fayeds appeared on the platform.
Ibari interrogated both men: her world’s primary Kareem and the “foreign” Kareem, who unexpectedly materialized from the Republic of California timeline.
Recognizing that the State planned to store foreign Kareem indefinitely in a desert labor camp, Ibari illegally rescued him using agent David Grissom’s credentials.
She established foreign Kareem in Los Angeles under his primary double’s identity, allowing him to raise Nico’s abandoned children, Marlowe and Samir, while acting as his covert handler for thirty years.
As primary Kareem grew distant and political, foreign Kareem embraced fatherhood and raised the children.
Thirty years later, on the night primary Kareem dies, Ibari transfers massive troves of classified State surveillance files onto a phone, gives it to foreign Kareem in the shantytown burn zone to leak online, and calmly surrenders to State police on the beach.

Chapter 3: Exit Wound
This chapter retells the pivotal spring 2031 party in Los Angeles from the perspective of the foreign Kareem Fayed. Hosting a party to celebrate the end of the California Republic curfew, Kareem is overwhelmed when two Sarayas appear, followed by a distressed woman named Nico who looks like his friend Gloria.
Fearing a mental breakdown, Kareem flees his own party to Santa Monica Pier, returns, and sits on his front steps with Ari, noting her “TRUE DILIGENCE” wrist tattoo.
When Kareem walks into his kitchen to retrieve wine, he steps through a spatial anomaly directly onto a platform in the UCLA physics lab in “The State” alternate universe.
There, he meets his primary double, who admits he lacks the courage to raise his children alone and intends to abandon them to join the Resistance.
Foreign Kareem steps into his double’s life, taking over the household and raising four-year-old Samir and three-year-old Marlowe with the guidance of Detective Ibari Waker.
Though initially disoriented by iris-scan economies and surveillance, foreign Kareem finds profound joy and fulfillment in being a loving father.
The novel concludes by linking fatherhood and existence back to Marlowe’s transport lecture: “What is transport? It’s the movement of matter through time and space. Incidentally, that’s also life”.
Part 3: SWAN DIVE
Swan Dive
In a brief historical coda set in a New York City art studio in 1960, painter Lucas Alkaitis works on a canvas depicting a diver’s feet plunging into a deep blue ocean.
He chats with his friend and professional rival, the painter Olivia, who is resting on his couch in a wine-stained red tweed coat.
They debate art, rivalry, and the transient nature of life.
Lucas reflects on his mother quoting poetry about how “it will not last the night,” realizing that the true purpose of existence is not durability, but appreciating how gorgeous the light is while it lasts.
