What happens when a writer stops running from the dark and starts mining it for gold?
For C. L. Sonnier, the answer is a debut dystopian sci-fi novel that hits closer to home than most readers will expect.
Under Martian Moons is not your average space opera. It’s a story born from real struggle. The kind that doesn’t announce itself dramatically but settles quietly into a life and changes everything. Sonnier, 37, is a self-described slow and intentional writer, a mom, a gamer, a dog-walker, and someone who spent years learning how her own mind worked before she could finally sit down and write the book she always knew was in her.
“When Was the Last Time You Felt Something Real?”
That question — the novel’s standout quote — is more than a line of dialogue. It’s a philosophical gut-punch that anchors the entire world Sonnier has built.
Set in a future where AI-powered computerized contact lenses interface directly with the human brain (think Neuralink, but weaponized), Under Martian Moons explores a society where emotion itself has become a liability. The technology, deployed by those in power, enables emotional erasure and information censorship on a mass scale. Freedom and control. Fate and free will. These are the tensions Sonnier weaves through every chapter.
“It’s intended for someone reading with curiosity and an open mind,” she says of her audience. The book ventures into territory that challenges comfortable assumptions — reincarnation, hidden forces shaping the masses — and Sonnier doesn’t apologize for that. She wrote it for readers who want to question the world around them, not be soothed by it.
The Personal Root of a Sci-Fi World
The technology in Under Martian Moons may be fictional, but its emotional logic is deeply personal. Sonnier was diagnosed as bipolar in her twenties, a discovery that set her on a years-long path of finding the right medications, learning her triggers, and building the kind of stability that doesn’t happen overnight.
“I found out I was bipolar in my 20s, so finding the right medications and learning my triggers to avoid episodes has been a struggle most of my adult life,” she shares. That lived experience fed directly into the novel’s central theme: how deeply emotions shape our decisions, and how dangerously malleable we become when those emotions are manipulated or erased.
The irony is not lost on her. The writer who spent years trying to regulate her emotions wrote a book about a world that tries to eliminate them entirely.


A Born Storyteller Who Took the Long Road
Sonnier has wanted to write since she was a child, which, by her own account, got her into trouble early. “Once I learned how to read, I decided I’d rather write my own stories than read what I was told to,” she laughs. Her third-grade teacher did not share her enthusiasm, warning that she’d have to learn from reading before anyone would want to read her writing. Sonnier ignored the advice. Eventually, life caught up and handed her the wisdom anyway.
Her twenties were full of started-and-abandoned projects. Self-doubt, instability, and the sheer momentum of mania made it hard to find balance. “I started many works in my twenties and allowed myself to get deterred and bogged down with doubt,” she says. “I’m more willing to stink now, to put in the work and carry on.”
The turning point came with motherhood. Something about having a son, who now joins her for walks with the dog, video games, and cooking, made Under Martian Moons finally feel possible. “I always wanted to write, but it always felt a bit out of reach until I had my son.”

Writing Slowly on Purpose
Here’s the thing that might surprise you most about C. L. Sonnier: she writes slowly, and she chose to.
In the past, the obsessive creative pull of a project triggered manic episodes. She would write for days straight, unable to stop, until — as she puts it — she “looked like the Mad Hatter.” The work cost her rest, health, and stability.
“I write very slowly now and it’s quite intentional,” she says. “Balance now is my key, and compass as a writer.”
That discipline, born from hard-won self-knowledge, shapes not just her process but the book itself. Under Martian Moons is a careful, considered work, not written in a frenzied burst, but excavated deliberately, the way she describes all her writing: mining for treasures that require deeper digging.
“Writing has mostly been an outlet for me to explore things that conversations can’t fully realize,” she reflects. “Without having done it, I think my understanding of life would be far less.”

What’s in a Name?
Sonnier writes under her initials C. L. rather than her full first name. It’s a practical choice: she has other work in a different genre waiting in the wings, unpublished, and she wants to keep those worlds separate for now. The initials create a clean boundary. They also lend the byline a quietly compelling ambiguity that suits a writer who doesn’t traffic in easy answers.
Under Martian Moons by C. L. Sonnier is available now. For readers who want their sci-fi to ask real questions about power, about freedom, about what it means to feel anything at all, this is the book waiting for you.


UNDER MARTIAN MOONS
By C.L. Sonnier
What if emotions were never yours to keep?
On an ancient Mars, peace is carefully controlled and dangerously fragile.
For eighty years, the city of Alora has thrived under the SAiLS system, neural implants tied to AI contact lenses that suppress fear, grief, and even love. Kader Atman, a loyal Guardian, has spent his life enforcing that order, believing it is the only thing keeping his civilization from chaos.
Until the system begins to fail. When citizens start experiencing raw, unfiltered emotion, panic spreads across the Martian city. At the same time, a mysterious outsider, banished to the barren desert, begins invading Kader’s mind. Forcing him to question everything he was trained to believe.
But the greatest threat isn’t the rebellion. It’s Lux Tal, the Director’s daughter, his past, and the one person his AI calibration system can’t fully erase.
As tensions rise and war looms between the controlled city and the exiled survivors beyond its borders, Kader must choose between duty and desire… before emotion tears his world apart.
Because on Mars, to feel is to rebel. And love may be the most dangerous rebellion of all.
