Overview
In ‘Sea of Tranquility,’ I wanted to weave together lives separated by centuries, connecting them through a single, inexplicable moment—a glitch in the fabric of reality. The story begins with an English exile in the Canadian wilderness in 1912, jumps to a woman grappling with the fallout of a Ponzi scheme in 2020, follows a novelist from a moon colony on a book tour during a pandemic in 2203, and centers on a man from the 25th century tasked with investigating the very nature of time itself. I wrote this book during our own pandemic, and it is deeply infused with the anxieties of that time: isolation, the fragility of our world, and our profound need for connection. My central question became: what if our reality is not what it seems? The novel explores the [[simulation hypothesis]], not as a bleak technological trap, but as a framework for understanding existence. It’s a story for anyone who has ever felt a sense of dislocation in their own time, who looks for patterns in the chaos, and who believes in the enduring power of art and love to give life meaning. Ultimately, I’m not trying to provide a definitive answer on whether we live in a simulation. Rather, I want to suggest that even if we do, the lives we lead—our joys, sorrows, and the beauty we create—are no less real or precious. It’s a novel about pandemics, but it’s also about time, memory, and the strange, beautiful, and sometimes terrifying interconnectedness of all things.
Book Distillation
1. Remittance / 1912
Edwin St. John St. Andrew, a young Englishman of noble birth, is sent into a kind of exile in the vast Canadian wilderness. He finds himself in the remote coastal settlement of Caiette. One day, feeling unmoored, he steps into the forest and experiences a strange rupture in his reality: a moment of total darkness, the sound of violin music, and the distinct feeling of being inside a massive, echoing terminal. He dismisses it as a hallucination, but the event is the first thread in a web that stretches across centuries.
Key Quote/Concept:
[[The Anomaly]]: The core mystery of the book is this momentary glitch in spacetime. It’s described as ‘a flash of darkness, like sudden blindness or an eclipse… an impression of being in some vast interior, something like a train station or a cathedral, and there are notes of violin music… and then an incomprehensible sound—’. This event serves as the nexus point connecting the novel’s disparate timelines and characters.
2. Mirella and Vincent / 2020
Mirella Kessler’s life was destroyed by a massive Ponzi scheme orchestrated by her friend Vincent’s husband. Years later, seeking answers, she attends a performance by Vincent’s brother, a composer, only to learn Vincent is dead. The composer plays a piece set to a video Vincent shot in the woods of Caiette, and the video contains the exact same glitch Edwin experienced. Mirella is approached by Gaspery Roberts, an investigator looking into the anomaly. The encounter triggers a memory for Mirella of a traumatic childhood event where she believes she saw this same man.
Key Quote/Concept:
[[The Echo of Trauma]]: The financial collapse acts as a personal apocalypse for Mirella, mirroring the larger cataclysms in other timelines. Her story explores how personal history, grief, and betrayal can create realities as disorienting and life-altering as any pandemic or supernatural event, raising questions about complicity and the impossibility of truly knowing another person.
3. Last Book Tour on Earth / 2203
Olive Llewellyn, a novelist from a moon colony, is on a book tour on Earth for her bestselling pandemic novel, ‘Marienbad’. As she travels, a real pandemic begins to spread. Her novel uncannily describes the anomaly, depicting a character in an airship terminal who experiences a flash of darkness and a vision of a forest. At her final tour stop, she is interviewed by Gaspery-Jacques Roberts, who knows about her personal experience with the anomaly and warns her to flee Earth immediately, proving his credibility by sharing a name she invented for her book.
Key Quote/Concept:
[[Art as Prophecy]]: Olive’s novel, ‘Marienbad’, isn’t just a story; it’s a piece of evidence. The fact that her fictional account of the anomaly perfectly matches other historical records becomes a key plot point. This explores the idea that art can tap into deeper truths, sometimes unknowingly, and that fiction can bleed into and shape reality.
4. Bad Chickens / 2401
Gaspery-Jacques Roberts grows up in the ‘Night City’ on the moon. His sister, Zoey, is a physicist at the Time Institute. She comes to believe they are living in a simulation, and presents Gaspery with the evidence: Edwin’s letter from 1912, Vincent’s video from the 1990s, and Olive’s novel from 2203 all describe the same anomaly, which she theorizes is a [[file corruption]] in their reality’s code. Seeking purpose, Gaspery joins the Time Institute as an investigator, tasked with traveling through time to understand the nature of this glitch.
Key Quote/Concept:
[[The Simulation Hypothesis]]: This is the central scientific theory that reframes the novel’s events. Instead of a supernatural or mystical occurrence, the anomaly is potentially a bug in the software of the universe. This hypothesis drives the plot, giving the Time Institute its purpose: to investigate and contain glitches that threaten the integrity of the timeline, or more accurately, the secrecy of the simulation itself.
5. Last Book Tour on Earth / 2203
Having been warned by the time traveler Gaspery, Olive Llewellyn flees Earth and returns to her family on the moon colony just as a devastating pandemic locks down society. Living through the reality she once wrote about as fiction, she grapples with her survival and the nature of her art. In a virtual lecture, she theorizes that apocalypse is not a singular event but a continuous process. From her apartment, she witnesses Gaspery and his sister Zoey arguing outside, realizing the profound consequences of his decision to save her life.
Key Quote/Concept:
‘What if it always is the end of the world?’: This is Olive’s philosophical proposition, delivered in a lecture. It challenges the narcissistic belief that one’s own era is uniquely perched on the brink of collapse. Instead, she suggests that humanity exists in a state of ‘continuous and never-ending’ crisis, a perspective that offers a strange form of resilience.
6. Mirella and Vincent / file corruption
Gaspery, now a fugitive for breaking protocol, is sent by his sister to Caiette in 1994. There, he witnesses the anomaly from a new perspective, simultaneously experiencing the forest of 1994, the airship terminal of 2203, and the presence of Edwin from 1912. He sees the ‘file corruption’ firsthand. He then travels to a 2007 art party to interview Vincent, confirming her memory of the event. He understands the terrible knowledge of a time traveler: knowing the tragic fates of those around him, and realizing his own is sealed.
Key Quote/Concept:
[[The Observer Effect in Time Travel]]: Gaspery’s journey highlights the paradox of being an investigator of the past. He is armed with the terrible foreknowledge of everyone’s death, which Zoey describes as a ‘troubling line of work.’ This knowledge creates an immense ethical and emotional burden, forcing the question of whether it’s possible to witness history without being destroyed by it.
7. Remittance / 1918, 1990, 2008
Upon returning to his own time, Gaspery is captured. The Time Institute, an organization primarily concerned with its own self-preservation, exiles him. He is drugged and abandoned in late 20th-century Ohio, framed for a double homicide he stumbles upon, and sentenced to life in prison. In this state, he is seen by a nine-year-old Mirella. Before his capture, Gaspery makes one final, unauthorized trip to 1918 to visit the shell-shocked Edwin St. Andrew, assuring him that his vision in the forest was real, giving the man a measure of peace.
Key Quote/Concept:
[[Bureaucracy as a Self-Protecting Organism]]: The Time Institute’s actions reveal its true nature. It doesn’t punish Gaspery for altering the timeline in a major way—saving Olive had minimal effect—but for threatening its secrecy and control. As a former employee tells Gaspery, ‘Bureaucracy exists to protect itself.’ This cynical realism grounds the high concept of time travel in the mundane, and often amoral, realities of institutional power.
8. Anomaly
Decades later, an elderly Gaspery is rescued from a prison hospital by Zoey, who now works for a rival time travel organization. She relocates him to a farm in 2172, where he lives out his life, eventually marrying Talia, a childhood acquaintance. In a final revelation, Gaspery understands that he himself is the anomaly. In 2195, as an old man playing a violin in an airship terminal, he is interviewed by his younger, naive self. The presence of two Gasperys in one place, combined with his connection to the other witnesses, triggers the ‘file corruption’ that ripples across time. The knowledge brings him peace.
Key Quote/Concept:
‘A life lived in a simulation is still a life.’: This is the novel’s closing thesis and ultimate takeaway. After all the investigation and existential dread, Gaspery concludes that the metaphysical nature of reality is irrelevant. The human experience—love, connection, art, a quiet life on a farm—is what holds meaning. The search for objective truth gives way to the subjective beauty of a life well-lived.

Essential Questions
1. How does ‘Sea of Tranquility’ explore the [[simulation hypothesis]], and what is its ultimate conclusion about the nature of reality?
In my work, I wanted to approach the [[simulation hypothesis]] not as a cold, technological puzzle, but as a lens through which to view human experience. The central mystery, [[The Anomaly]], is initially presented as a supernatural or inexplicable event. However, through the work of Zoey and the Time Institute, it’s reframed as a potential ‘file corruption’—a glitch in the code of our universe. This provides the narrative engine for Gaspery’s investigation across centuries. My purpose wasn’t to definitively prove or disprove the hypothesis. Instead, I use it to ask a more profound question: if our reality is a construct, does that diminish the value of our lives? The conclusion, reached by Gaspery in his final years, is a resounding ‘no.’ He realizes that the metaphysical framework is irrelevant. The love he shared with Talia, the quiet life on the farm, the beauty of art—these experiences are intrinsically real and meaningful. The ultimate implication is that meaning is not found in the objective nature of reality, but in the subjective quality of the lives we lead within it. A life lived in a simulation is, after all, still a life.
2. What role does art play in connecting the characters and driving the narrative forward?
Art is the connective tissue of this novel, the very thing that proves the interconnectedness of these disparate lives. It functions as both prophecy and evidence. Olive Llewellyn’s pandemic novel, ‘Marienbad,’ isn’t just a story; it’s a historical document that unknowingly records [[The Anomaly]]. Her fictional description of a man in an airship terminal experiencing the glitch becomes a key piece of evidence for the Time Institute. Similarly, the violin music—a lullaby composed by an older Gaspery for his wife—echoes through the anomaly, heard by Edwin in 1912 and woven into Paul Smith’s composition in 2020. This demonstrates how art can transcend time, carrying emotional truth and information across centuries. It suggests that artists, in their attempts to capture some essential truth about the human condition, sometimes tap into the fundamental structure of reality itself, even if that reality is a simulation. Art becomes the ghost in the machine, a pattern that reveals the underlying code.
3. How does Gaspery’s journey challenge the ethics of time travel, particularly the conflict between protocol and humanity?
Gaspery’s story is a deep dive into the ethical minefield of time travel. The Time Institute operates under a strict, almost inhuman protocol: observe but do not interfere. This is rooted in a desire to protect the timeline, but as Talia reveals, it’s more about protecting the institution itself. Gaspery is confronted with what his sister Zoey calls a ‘troubling line of work’: possessing the foreknowledge of every person’s death. This creates an unbearable emotional burden. The central conflict arises when he meets Olive Llewellyn, a woman he knows is fated to die in a pandemic. His decision to break protocol and warn her is an act of pure humanity, a rebellion against the cold logic of his training. The consequences are severe—he is exiled and framed for a crime—but he never regrets it. His journey suggests that a purely observational, detached approach to history is not only difficult but perhaps morally indefensible. It forces the question: what is the point of safeguarding a timeline if you must sacrifice your own humanity to do so?
Key Takeaways
1. A Life Lived in a Simulation Is Still a Life
This is the novel’s central thesis, the quiet revelation that Gaspery reaches at the end of his long, strange life. After grappling with the existential dread of the [[simulation hypothesis]], investigating the ‘file corruption,’ and being punished for altering the timeline, he finds peace not in understanding the grand mechanics of the universe, but in the simple, tangible joys of his own existence. The book supports this by contrasting the high-concept sci-fi plot with deeply personal, human moments: Gaspery’s love for his wife Talia, Olive’s fierce love for her daughter, Edwin’s search for peace. It argues that the source of reality is less important than our experience of it. Whether our world is ‘base reality’ or a complex program, the emotions we feel, the connections we forge, and the beauty we perceive are authentic. The search for objective truth ultimately gives way to the profound meaning found in a subjective life, well-lived.
Practical Application: For an AI product engineer, this is a crucial reminder about user experience and the nature of digital worlds. As you build more immersive AI-driven environments or virtual realities, remember that the ‘realness’ of the experience for the user is what matters. The technical backend is the means, not the end. The goal is to create systems that facilitate genuine connection, emotion, and meaning for the people within them, because the feelings and relationships formed in a digital space are, to the participants, entirely real.
2. Bureaucracy’s Primary Function Is Self-Preservation
The Time Institute, for all its noble-sounding mission of ‘safeguarding the integrity of our time line,’ is ultimately a bureaucracy. Through the character of Talia, a former insider, I reveal its true nature. The Institute’s harshest punishments are reserved not for those who accidentally alter history, but for those who threaten its secrecy and control. Gaspery’s ‘crime’ wasn’t saving Olive Llewellyn—an act that had minimal impact on the timeline—but breaking protocol and exposing the Institute’s methods. As Talia states bluntly, ‘Bureaucracy exists to protect itself.’ This grounds the fantastical concept of time travel in a cynical, recognizable reality. It’s a commentary on how large organizations, whether governmental or corporate, can lose sight of their original purpose, becoming self-perpetuating systems where maintaining power and secrecy becomes the primary objective, often at great human cost.
Practical Application: An AI product engineer working in a large tech company should be wary of this dynamic. Your team or company may have a lofty mission statement, but always analyze its actions. Are decisions being made to serve the user and the mission, or to protect the organization’s reputation, consolidate power, or avoid uncomfortable truths? Recognizing when [[organizational inertia]] and self-preservation are driving product decisions, rather than user needs or ethical principles, is a critical skill for navigating corporate life and advocating for better products.
3. Apocalypse Is a Continuous, Never-Ending Process
This idea, articulated by Olive during a virtual lecture in the midst of a pandemic, challenges our ‘kind of narcissism’—the belief that our specific moment in history is uniquely catastrophic. She posits, ‘What if it always is the end of the world?’ The novel supports this by weaving together multiple crises across centuries: Edwin’s exile and the trauma of war, the devastation of a Ponzi scheme for Mirella, and multiple pandemics. Each of these events feels like an apocalypse to the people living through it. By connecting them, I wanted to suggest that humanity has always lived in a state of rolling crisis. This perspective is not meant to be bleak; rather, it’s a source of resilience. It reframes our contemporary anxieties, suggesting that navigating catastrophe is not a new challenge but a fundamental part of the human condition. It encourages a sense of continuity with the past and a more measured perspective on the crises of the present.
Practical Application: In the fast-paced world of AI development, it’s easy to get caught up in the hype and fear of the ‘next big thing’ being an existential threat or a world-ending disruption. This takeaway encourages a historical perspective. Technological disruption, societal anxiety, and fears about the future are not new. By studying past technological shifts and their societal impacts, an AI product engineer can better anticipate the real challenges and opportunities of AI, separating the cyclical patterns of human anxiety from the unique characteristics of the current technology, leading to more grounded and less reactive [[product strategy]].
Suggested Deep Dive
Chapter: Bad Chickens / 2401
Reason: This section is the intellectual core of the novel. It’s where the disparate, seemingly supernatural threads are woven together into a coherent scientific mystery. Through Gaspery’s conversation with his sister Zoey, we are formally introduced to the [[simulation hypothesis]] as the driving theory behind the events. She presents the three key pieces of evidence—Edwin’s letter, Vincent’s video, and Olive’s novel—and reframes [[The Anomaly]] as ‘file corruption.’ This chapter establishes the stakes, the methodology of the Time Institute, and Gaspery’s personal motivation for undertaking his journey. It’s essential for understanding the shift from a literary mystery to a science fiction investigation.
Key Vignette
The Anomaly in the Forest
In 1912, a young, exiled Englishman named Edwin St. John St. Andrew wanders into the coastal forest of Caiette, on Vancouver Island. Seeking to project an air of purpose, he steps into the woods and is suddenly overcome by a sensory rupture. For a moment, he is plunged into darkness, hearing the distinct sound of violin music and feeling the overwhelming impression of being inside a vast, modern terminal, like a train station or cathedral. The moment passes as quickly as it came, leaving him vomiting on the beach, convinced he’s losing his mind. This event is the novel’s inciting incident, the first documented occurrence of the ‘glitch’ that connects all the timelines.

Comparative Analysis
My novel, ‘Sea of Tranquility,’ naturally draws comparisons to my earlier work, ‘Station Eleven,’ as both grapple with pandemics and the resilience of art in times of crisis. However, where ‘Station Eleven’ was grounded in a post-apocalyptic Earth, ‘Sea of Tranquility’ expands the canvas to centuries and colonies on the moon, using science fiction tropes like [[time travel]] and the [[simulation hypothesis]] to explore similar themes of connection and meaning. The book’s structure, with its interwoven timelines converging on a single mystery, might remind readers of David Mitchell’s ‘Cloud Atlas.’ Both novels demonstrate how individual lives, separated by vast gulfs of time, can unknowingly influence one another. Yet, my focus is perhaps less on a karmic cycle and more on a shared, simultaneous reality, bound by a single technological framework. Unlike the hard, speculative science fiction of an author like Ted Chiang, whose ‘Stories of Your Life and Others’ delves deep into the scientific and linguistic implications of its concepts, my novel uses its sci-fi premise primarily as a vehicle to explore deeply human, emotional questions. The technology of time travel is less important than the ethical and emotional weight it places on the traveler. Ultimately, it’s a story that uses the grand scale of science fiction to arrive at an intimate, humanistic conclusion.
Reflection
Writing ‘Sea of Tranquility’ was my way of processing the profound sense of dislocation and anxiety of the early pandemic. The novel is a reflection of that time, filled with themes of isolation, contagion, and the search for meaning in a world that suddenly feels fragile and unreal. Its strength, I believe, lies in this emotional core; it’s a science fiction novel that is less concerned with the ‘how’ of its technology and more with the ‘why’ of human endurance. The interwoven structure, which some might find complex, is intended to create a sense of cosmic connection, showing how a single moment can ripple across five hundred years. A skeptical reader might argue that the [[simulation hypothesis]] is treated more as a metaphor than a rigorous scientific concept, and they would be right. My interest is in its philosophical implications, not its technical plausibility. The book intentionally diverges from hard fact to explore a more lyrical, speculative truth about our reality. Its weakness, perhaps, is that it offers comfort rather than answers. But in a time of great uncertainty, I felt that exploring the idea that life is precious and meaningful—regardless of its underlying nature—was the most significant contribution I could make. It’s a quiet, hopeful book written in a loud, frightening time.
Flashcards
Card 1
Front: What is [[The Anomaly]] in ‘Sea of Tranquility’?
Back: A momentary glitch in spacetime where individuals in different centuries simultaneously experience being in two places at once: a forest on Vancouver Island and a vast indoor terminal (the Oklahoma City Airship Terminal), accompanied by darkness and violin music.
Card 2
Front: What is the Time Institute’s official purpose, and what is its actual primary motivation?
Back: Official Purpose: To safeguard the integrity of the timeline by investigating anomalies. Actual Motivation: Self-preservation. As a bureaucracy, its main goal is to protect its own existence, secrecy, and control, even at the expense of its agents or the timeline itself.
Card 3
Front: Who are the three primary historical witnesses to [[The Anomaly]] that Gaspery investigates?
Back:
- Edwin St. Andrew (1912): An English exile who experiences it in a forest. 2. Vincent Smith (1994): A teenager who captures it on video. 3. Olive Llewellyn (2203): A novelist who experiences it in an airship terminal and writes about it in her book ‘Marienbad’.
Card 4
Front: What is the central theory that Zoey proposes to explain [[The Anomaly]]?
Back: The [[simulation hypothesis]]. She theorizes that reality is a simulation and the anomaly is a ‘file corruption,’ where moments (files) from different centuries are bleeding into one another.
Card 5
Front: What is Gaspery-Jacques Roberts’s ultimate role in the story’s central mystery?
Back: He is the cause of the anomaly. As an old man playing the violin in the airship terminal in 2195, he is interviewed by his younger self. The presence of two Gasperys in one place, combined with his temporal connection to the other witnesses, triggers the ‘file corruption’ that ripples through time.
Card 6
Front: What is Olive Llewellyn’s theory of ‘continuous apocalypse’?
Back: The idea that humanity is always living through some form of world-ending crisis. It challenges the narcissistic belief that one’s own era is uniquely catastrophic, suggesting instead that apocalypse is a ‘continuous and never-ending process.’
Card 7
Front: What is the ultimate ethical choice Gaspery makes?
Back: He chooses humanity over protocol by breaking the Time Institute’s rules to warn Olive Llewellyn of the coming pandemic, thereby saving her life but sealing his own fate as a fugitive from the Institute.
