There is a prejudice so embedded in Western culture that most people never think to question it: the assumption that the ability to speak is a prerequisite for the ability to think. Angie Kim’s second novel, Happiness Falls (Hogarth, 2023), dismantles this assumption with the precision of a legal brief and the emotional force of a family thriller. The book arrived in August 2023 to immediate acclaim – an instant New York Times bestseller, a Good Morning America book club pick, a Barnes & Noble book club pick, and Oprah Daily’s number one novel of 2023. But its significance extends well beyond the bestseller lists. Kim has produced what may be the first mainstream literary novel to centre a nonverbal protagonist who communicates through spelling, doing so in a way that is neither sentimental nor reductive.
The novel opens with a disappearance. Adam Parson, a white American father and full-time carer, takes his 14-year-old son Eugene for a morning walk in a park near their home in Great Falls, Virginia, outside Washington DC. Only Eugene returns. He cannot tell his family what happened – not because he does not know, but because he has autism and Angelman syndrome, a rare genetic condition that severely limits motor control, including speech. Eugene’s family – his Korean-born mother Hannah, a linguist; his 20-year-old twin siblings Mia and John – are thrown into crisis, forced to confront both the mystery of Adam’s disappearance and their own assumptions about what Eugene understands.
From Courtroom to Living Room
Kim’s debut, Miracle Creek (2019), established her as a formidable practitioner of the legal thriller. That novel, told from seven rotating perspectives, centred on the explosion of a hyperbaric oxygen therapy chamber in rural Virginia, killing two people and triggering a murder trial. It won the Edgar Award for Best First Novel, the ITW Thriller Award for Best First Novel, and was named by Time as one of the 100 best mysteries and thrillers of all time. Translated into more than 20 languages, it announced a writer with an unusual ability to fuse procedural suspense with intimate domestic portraiture.
Happiness Falls marks a deliberate narrowing of focus. Where Miracle Creek sprawled across a cast of characters and a courtroom, Kim’s second novel is told entirely from the first-person perspective of Mia Parkson, the sharp, sardonic 20-year-old twin sister. The constraint is intentional. As Kim told NPR’s Scott Simon in August 2023, staying with Mia throughout provides “a literary taste of what it might feel like to live through a missing-person case, the fear that you might never know what happened to this person you love.” The claustrophobic intimacy of Mia’s narration also functions as a structural argument: by locking the reader inside one perspective that cannot access Eugene’s, Kim replicates the communicative isolation that nonverbal individuals experience daily.
The Immigrant Parallel
What distinguishes Kim from a novelist who might tackle disability as an exercise in empathy tourism is the deeply personal origin of her engagement with nonverbal communication. Kim moved with her family from Seoul, South Korea, to the suburbs of Baltimore when she was 11 years old. She spoke no English. The experience left a permanent mark.
“I became a different person in English,” Kim wrote in a January 2024 essay for The Guardian. “Back in Seoul, I had been a confident, outgoing girl. In Baltimore, I was a bah-bo. Stupid, timid and, most of all, ashamed. I recognised for the first time the deep-seated prejudice so many of us carry: we equate verbal fluency with intelligence.”
This childhood wound, Kim has explained repeatedly across interviews, became the emotional engine for her fiction. After studying philosophy at Stanford University and attending Harvard Law School – where she was an editor of the Harvard Law Review – Kim practised litigation, then management consulting, then co-founded a startup, then spent years as a stay-at-home mother to three sons with various medical conditions. She did not publish her first novel until the week she turned 50. The long gestation is evident in the maturity of her prose: Kim writes with the authority of someone who has accumulated decades of professional and personal experience before committing it to the page.
The Speller Community
The catalyst for Happiness Falls was a moment Kim witnessed at a medical conference nearly two decades ago, where a doctor described a non-speaking autistic teenager whose teachers had concluded his repetitive behaviours – screaming, head-banging – were “purely behavioural.” As the doctor recounted this, the boy grabbed his sister’s alphabet toy and typed: help me it hurts.
Kim was shaken. Through her son’s own medical treatments, she had encountered a community of parents of children with conditions ranging from autism to cerebral palsy. She began researching communication therapies that approached nonspeaking as a motor challenge – apraxia – rather than a cognitive deficit. The approach, sometimes called spelling to communicate, involves teaching individuals to point to letters on a letterboard, one letter at a time. What emerged from these sessions stunned Kim: essays about history, poetry, and the experience of being imprisoned in one’s own body, all composed in polished, literary prose.
The scientific basis for these therapies has been contested, with some critics characterising them as facilitated communication – a discredited practice in which a therapist, not the nonspeaking individual, selects the letters. Kim engaged directly with this scepticism. She cited a 2020 peer-reviewed study published in Scientific Reports, by researchers at the University of Virginia, which used eye-tracking technology to monitor non-speaking autistic spellers during letterboard communication. The study found that participants were looking at and selecting each letter independently, not following a therapist’s cues. Kim went further: she began teaching creative writing to groups of nonspeaking spellers, sitting beside them as they used letterboards to answer her prompts and compose their own work.
“It amazed me to see these children writing such beautiful, intelligent thoughts once given the chance – once we stopped underestimating their abilities,” Kim told the Faber journal in July 2024.
The Novel’s Architecture
Eugene, the nonverbal character in Happiness Falls, is not the narrator. He cannot be. This is the novel’s most consequential structural decision and its most pointed thematic statement. By making Mia – articulate, hyperverbal, convinced she knows everything – the sole narrator, Kim forces the reader to experience Eugene’s intelligence from the outside, filtered through a sister’s evolving understanding. The reader never gets direct access to Eugene’s thoughts, which mirrors the real-world barrier that nonverbal individuals face: their interiority exists, but it requires effort, patience, and specific tools to access.
Kim considered writing from Eugene’s perspective but concluded that staying with Mia provided greater literary power. The claustrophobia of Mia’s limited view – her anxiety, her bewilderment, her guilt about resenting the time and energy Eugene consumes – becomes the reader’s own. As Kim explained to Country and Townhouse magazine: “Staying with one character – the claustrophobic isolation, anxiety, and bewilderment – provides a literary taste of what it might feel like to live through a missing-person case.”
The novel’s central question – what happened to Adam – functions as a Trojan horse. It draws readers in through the mechanics of a thriller, then implicates them in the same epistemological crisis the family faces: how do you determine truth when one of the key witnesses cannot speak? The book thus becomes an allegory for the epistemological problem at the heart of the speller debate itself. If you cannot hear someone’s account, do you assume they have none?
Beyond the Page
Kim’s advocacy for nonverbal individuals extends beyond the novel’s pages. For the audiobook of Happiness Falls, Eugene’s words were read by “Autastic Tom” Pruyn, a speller who can vocalise written text. At multiple book events, spellers served as Kim’s conversation partners on stage. In other appearances, spellers in the audience used letterboards to comment and ask questions, prompting visible astonishment from other attendees. Spellers have participated in the novel’s book clubs and written reviews – acts of participation that Kim has described as “generous acts of support.”
These are not peripheral activities. They represent an attempt to model a different kind of public literary culture, one in which nonverbal individuals are not merely represented but are active participants in the conversation about their own representation. Kim’s creative writing classes for nonspeakers, which she continues to teach, function as a practical extension of the novel’s argument: that nonverbal individuals possess rich interior lives that emerge the moment they are given adequate communicative tools.
A Structural Critique
What makes Happiness Falls more than a well-intentioned novel about disability is its insistence that the problem is structural, not individual. The novel does not ask readers to feel sorry for Eugene. It asks them to examine why a society that prides itself on inclusion has systematically excluded an entire population from the category of “thinking person” based solely on the absence of speech. Kim frames this not as a failure of compassion but as a failure of epistemology – a deeply ingrained cognitive bias that equates the vehicle of communication with the presence of thought.
The novel’s critical and commercial success suggests that this argument has found an audience. But Kim’s broader project – shifting cultural assumptions about nonverbal intelligence – depends on more than a single book. It depends on the speller community’s continued visibility, on the growing body of scientific research supporting letterboard communication, and on the willingness of other writers to engage with these questions. Happiness Falls is not the final word. It is, perhaps, the first loud one.
Happiness Falls sits within a growing body of literary fiction exploring neurodivergence and empathy in contemporary culture. For more on the themes of representation and voice in literature, see our Literature section.
