Bowler considers her own relationship with joy, citing recent experiences. One weekday morning, Bowler was woken by her son, Zach, who slipped through the bedroom door wrapped in a blanket she keeps trying to give away. Zach asked about her dream—she was being pulled behind a boat and couldn’t let go—then asked whether children can practice using grenades and requested that the family purchase a zeppelin, prompting Bowler to resolve to speak to her father about the military history topics dominating his nightly Zoom calls with Zach.

A cup of coffee offered Bowler a moment of gratitude before she began her workday at her desk, facing an overflowing inbox and a to-do list that spiraled from calling the pharmacy into a password-recovery labyrinth. She lists the day’s other concerns: monitoring a suspicious mammogram result, praying for her Best Friend’s troubled relationship, and fielding her mother’s surgery updates. Ultimately, she found genuine calm in her historical research.

Bowler reflects that 10 years have passed since her diagnosis—she is technically cancer-free but carries the health problems of someone much older. Suffering, she observes, removes ignorance and arrogance, but it functions as a loss rather than a gift. She tells her psychologist, Henry, that she feels perpetually alert in a way that isn’t useful; he suggests this may not qualify as a disorder given that her fears are concrete. She connects the feeling to Martin Heidegger’s concept of “thrownness”—the inability to choose one’s future. The chapter ends with Bowler catching herself judging others for being oblivious to suffering, then realizing that she too has been consumed by mundane problems like her inbox. In reflection, she feels guilty for having been so transformed by cancer, and yet not transformed enough.

Bowler describes the tradition she and her Best Friend share of weekend getaways that function as intensive therapy sessions. She describes one such retreat. After a full itinerary of screen-printing, brunch, massages, and a folk dance called contra dancing, the two found themselves sitting in a parked car in the pouring rain on their final evening, both stuck in their own loops. Bowler was mired in chronic pain, repetitive health appointments, work bureaucracy, and the same argument with her husband on rotation. Her Best Friend had a different problem.

Three years earlier, her Best Friend met a man while both were substitute teachers. He was unavailable—already in a relationship—but they maintained a daily friendship that gradually clarified into something more. The Best Friend eventually recognized that she was involuntarily memorizing his particular qualities, from his scent to the sound of his voice. In the car, she quietly admitted she could stay in this undefined arrangement indefinitely. The friend’s situation calls to mind Antoine de Saint-Exupéry’s fox, who warns the little prince how exchanges become habits, habits become expectations, and expectations forge mutual need.

Bowler expressed worry that the situation was hurting her friend; her friend pushed back. Together they gave a name to the feeling: “the ache.” Bowler defined it broadly—a fleeting heartbreak, a persistent longing never resolved by productivity or routine, an unanswerable question about feeling known, loved, valued, or complete. The ache, she concludes, is durable and unrelenting, like a well that refills no matter how much one drinks from it.

Bowler presents a list of her fears. The eight items range from cancer and anxiety to global helplessness, lost friendships, social media pressure, pharmaceutical advertising, the eventual death of her father, and, finally, the ache itself.

Bowler opens with a childhood memory of playing Hungry, Hungry Hippos with her sisters, using the image of insatiable marble-swallowing as a metaphor for universal human wanting. She introduces the untranslatable Portuguese word saudade—a melancholic feeling of incompleteness—and notes that nearly every culture has produced music centered on longing, from the blues to flamenco to ghazals.

Drawing on a range of thinkers, Bowler argues that this perpetual yearning is intrinsic to the human condition. Saint Augustine, Glennon Doyle, and Friedrich Schiller (who named the feeling Sehnsucht) all described it as an ache for something never quite possessed. The Stoic Seneca called it a curse. Bowler counters that the gap is everywhere—in job loss, miscarriage, estrangement, and unrealized purpose. No self-help regimen, she argues, can solve the problem of human finitude, and the resulting shame only compounds the suffering, as Kierkegaard observed. She concludes that humans are troubled guests on a dark earth.

Bowler opens with a family truth passed down to her: Unforgivable things happen without apology. Her grandmother demonstrated this by sailing to Canada at 14 to find the father who had abandoned her, only to learn he had drowned.

Bowler applies the same truth to her own father. Throughout her childhood, Bowler’s father lived with depression—sleeping and napping in darkened rooms, his presence dampening the household with a need for silence. The family tiptoed around him. Bowler reframes what could have been said plainly: He was clinically depressed, his life overshadowed by what Carl Jung called his “shadow side.” He himself later recalled little of those years beyond glimpses of his daughters growing up.

This experience taught Bowler that everyone carries struggles invisible to others—what Thomas Hardy described as iron in the soul. In college, she encountered the psychological “set point” theory, which holds that baseline happiness levels are largely hardwired—a reasonable theory, she notes, unless your set point drags you downward. What she remembers most is a moment of black humor: Her father would chant “Jerry! Jerry! Jerry!”—borrowed from the television program—as a private signal to himself that today he would get up and try again. She found the beauty in that effort astonishing.

Bowler presents 11 responses she received when she asked people online to describe their longings. The answers include one more moment with a deceased son, financial peace, a sense of home, a dog’s immortality, a single pain-free day, a genuinely available friend, a cure for regret, allergy relief, family harmony, a respected career, and potato chips.

Bowler describes her experiences in academia, including her study of America’s foundational myths of health, wealth, and happiness. She then recounts her experience speaking at a fundraiser against human trafficking. At the fundraiser breakfast, she impulsively invited a bored stranger to join her on a road trip. A historian and podcaster, the man named Tom Holland, agreed.

After a long walk, the two ended up at Jack London State Historic Park, where the famous author Jack London and his wife, Charmian, built their dream home and eventually were buried. At the museum, Bowler read London’s famous manifesto—preferring ashes to dust—and became furious upon learning that London had abandoned his wife and two daughters to pursue his adventures with Charmian.

That evening, delivering her lecture, Bowler connected London’s story to the broader American myth that totalizing happiness is available to those who want hard enough. She argued that while men like London could devour the world and be celebrated for it, women faced the opposite calculus. She invoked other thinkers as she questioned who would acknowledge the true cost paid by those who abandoned their dreams out of love and obligation.

Bowler uses the metaphor of a house to describe how people walk others through their lives room by room, accumulating loves, responsibilities, and evidence of every choice made and inherited. She introduces the word “quiddity” to describe the specific nature of a life lived in full particularity. The walls of any life, she argues, are the obligations that accrue until they become load-bearing structures. She gives the example of a physically powerful friend who lifts weights because his daughter has a brain tumor and he needs to be strong enough to carry her. 

Bowler reflects that we worry over immovable problems and are in turn sheltered by others. At the same time, she feels constrained by her walls: bills, her loved ones, and a body that won’t cooperate. Citing a medieval dictum, she admits her life feels simultaneously too full and too empty—a truth she keeps folded away like a quilt in a closet.

Bowler offers 15 possible causes of the ache, including unborn children, fear for those who were born, worry about ecological collapse, anxiety about exes, early parental loss, chronic illness, missed travel, and the belated recognition that one perpetually sacrifices the present moment to obligation or pain. She argues that such examples prove that everyone is intimate with the ache.

Bowler imagines being a woman at effortless peace with her life—then returns to the reality of her workplace, Duke University, whose neo-Gothic campus she loves. Hired at 28 to teach graduate students near her own age, she adopted a scholarly persona to appear sufficiently professorial.

For over 15 years, Bowler has taught a course on toxic positivity. In it, she explores how Americans are becoming unhappier every year, particularly those under 30, while remaining culturally devoted to optimism. Modern positivity, she argues, is a multi-billion-dollar industry built on insecurity, dating back to 19th-century success manuals. Its social rules make expressing negative emotions unacceptable, pushing people toward masking or bypassing genuine feeling. She cites Alexander Schmemann’s view that America’s compulsory cheerfulness is a surface-level harmony, and Lisa Damour’s counterproposal that mental health is feeling emotions that fit a situation rather than feeling happy all the time.

Bowler asserts that she believes every word of her positivity lectures, which are backed by a decade of research. Yet she privately admits she still longs for a deep sense of sufficiency—and remains too overwhelmed by school pickups, physical therapy, and faculty meetings to pursue it.

Bowler describes a curated dinner she attends in Washington, DC. It is organized around strict rules—no small talk, no last names, no being boring—with a group of strangers. A man she privately dubs “the puma,” a successful entrepreneur with an unfazed manner, leads a thought exercise with three sequential questions.

Every hand goes up to confirm that everyone needs to change something. No hands rise with any confidence when asked who is happy. The third question—whether the group would follow a guaranteed formula for complete emotional, mental, physical, and spiritual health—produces hesitation. A climate scientist at the table breaks the silence to describe humanity’s willful self-poisoning despite having the knowledge to reverse environmental damage. A former surfer turned health-wearables CEO says he would take the formula to maximize his potential. The moderator, who is caring for a mother with early-onset dementia, breaks her own rules to say she wants it, too. Despite her principled skepticism toward such formulas, Bowler feels the familiar weight of her own wanting and raises her hand.

Bowler lists six failed remedies for the ache, including Instagram, oversized water bottles, professional compliments, spa visits, parenthood, and Jesus. She notes that while Jesus is the greatest source of love she knows, his existence is not a solution to the problem of pain—and she has a few suggestions she plans to raise when she arrives in heaven.

Bowler reflects on the type of person the dinner revealed: wellness elites and decamillionaires who pursue measurable optimization as a substitute for meaning. A new industry devoted to extending health and lifespan has emerged, populated by people who do not experience themselves as suffering. She recalls meeting a millionaire at a party who planned to become the longest-living person in history and consumed his last meal at 11 in the morning to optimize digestion and sleep quality. He described himself as maximizing his potential for happiness like everything else, prompting Bowler to coin the species name “Homo immortalitatis cupidus.”

She compares them to the prosperity gospel televangelists she studied for an earlier book, such as Kenneth Copeland, who announced he would not die until 2056. Both groups claim to have solved the ache. Their formula is simple: Improve everything, then repeat. In their telling, happiness is entirely predictable and available to anyone willing to try hard enough. There is, Bowler concludes, no mystery in this worldview—only effort.

Seeking a more substantive answer to the ache, Bowler has a Zoom call with Father Ron Rolheiser, a Canadian theologian at the Oblate School of Theology who is nearing 80 and managing advanced colon cancer. Bowler readily asks Father Ron about the ache.

Father Ron calls the phenomenon “the most basic thing about us” (70), invoking Saint Augustine’s argument that human existence is defined not by thought but by desire. Longing, he insists, is the deepest truth in everyone’s life, whether acknowledged or not. Bowler responds by confessing her accumulated frustrations: Life has not felt as meaningful as she expected after surviving cancer, and she lies about how she feels. She cannot achieve the perfection modeled by those who claim to have solved happiness, and her real accomplishments feel too small against the losses that keep accumulating.

Father Ron reframes everything. He says that because humans are made in God’s image, the restless, consuming fire inside them is divine. He calls it a “holy longing.” Bowler pushes back: She was taught that genuine faith eliminates longing. Father Ron acknowledges this but echoes Karl Rahner’s idea that, in this world, no symphony is ever finished. When Bowler asks what to do with so much unfulfilled desire, Father Ron describes spirituality as the practice of directing that energy toward worthy aims.

Bowler then confesses her specific struggle: She functions well in a crisis but finds ordinary life unbearable. Father Ron tells her plainly that we will all die with hopes unfulfilled. However, he offers one path through: If she can mourn it, she can live with it. The grief must be named rather than bypassed. Bowler realizes there is no shortcut to this wisdom. She resolves to stop looking for one and instead turn toward the ache and say yes.
