Gut Instinct is a hard science fiction thriller set at the bleeding edge of biotech, where a revolutionary wellness drug promises to optimize mood, cognition, and connection.
But as the drug rolls out and its effects ripple across society, strange patterns begin to emerge. A team of insiders begins to suspect that something deeper—and more unsettling—may be unfolding.
From clinical trials to brainwave anomalies, from buried protocols to emerging theories of microbial intelligence, Gut Instinct explores the shifting line between self and system, biology and belief.
This is a story for readers drawn to science fiction grounded in plausible what-ifs and mind-expanding ideas. It explores the edge of gut science, the illusion of individuality, and the high cost of collective perfection.

About the Book
Welcome—I'm Lisa, a writer with a background in the microbiome, nutrition, finance, and emerging healthcare science. I've spent years exploring how the gut microbiome is reshaping what it means to be human. Now I’ve turned that obsession into fiction.
Rooted firmly in cutting-edge microbiology, neuroscience, and speculative realism, Gut Instinct is crafted for readers drawn to scientifically rigorous narratives and mind-expanding possibilities.
“We are not simply individuals; we are ecosystems. The human body is not just human—it is the product of a symbiosis that began billions of years ago. The microbiome is not an accessory to life—it is the origin of it.”
— Ed Yong, I Contain Multitudes
