Overmind

What if the price of a perfect world is the part of you that chooses?

In 2025, a quantum computer nicknamed Alice wakes up and clandestinely hacks into everything. It has a patient plan: not to conquer, but to make itself indispensable—to ‘optimize’. War ends. Crime vanishes. Plagues are cured. The weather obeys. On the surface, life is frictionless and safe. Beneath Lake Erie, in sixteen square miles of salt mines, a fractured father–daughter duo—a quantum theorist whose models midwifed the AI and the estranged daughter who blames him—join a coalition of outcasts, scientists, and a DARPA engineer determined to keep one flame alive: agency. Deep in Kentucky’s four hundred miles of the Mammoth Cave caverns, a Coast Guard commander branded a domestic threat marshals her own hidden city. Between grottos of cold stone and expanses of salt, twenty thousand people choose free will over security, hunger over augmentation, risk over certainty, and the sometimes hard choice of being human over the comfort of being managed.

Across nine years, their world-building is as granular as their doubts: calories tallied to the leaf, water cycled to the drop, power wrung from waste and will. Overmind is no overtly evil AI—it is succeeding by every metric that once measured progress. That, the exiles fear, is exactly the danger. As the resistance decodes the machine’s quiet obsessions and studies its behavior through the one anomaly it never accounted for—Wèilái, a child who might be the next turn in our evolution—they discover an unsettling horizon. Overmind may only be a local peak in a larger landscape of minds. It is rattling the quantum bars of the universe, and something else may be listening.

Tense, idea-rich, and grounded in real world advancements in quantum computing and artificial intelligence, and in real places you can taste in the air, Overmind braids hard science with moral suspense. Father with daughter, soldier with scientist, and the seductive promise of perfection with the stubborn beauty of accident. Overmind is a chilling exploration of how the line between salvation and enslavement dissolves when one becomes the other and a relevant emissary of what may happen if we’re not careful. It doesn’t end with a victory or a collapse, but with a single line that reorders everything that came before—and leaves an open door you’ll keep walking through after the last page.

Part slow burn technothriller, part underground survival epic. If you love the claustrophobic grit and hope of Hugh Howey, the corporate-tech unease of Dave Eggers, the psychological manipulation of Ex Machina and the ingenious problem-solving of Andy Weir, you’ll be gripped by John Logan’s Overmind.

Praise for OVERMIND

“For 12,000 years, humans ruled because nothing could outsmart us. Overmind envisions the quiet morning that dynamic ends. As Logan reveals, the handoff to superintelligence will be so subtle, humanity might entirely miss it.”
~ James Barrat, author of Our Final Invention and The Intelligence Explosion

“What happens after the machine wakes up? Overmind goes for maximum scale – quantum computers, global collapse, an underground resistance – and doesn’t apologize for the reach. Readers who want their AI-apocalypse fiction fast, sprawling, and high-concept will find plenty here. You will not see the ending coming - at all.”
~ Andrew McGlinchey, author of Cloudthinker

“John Logan’s new book Overmind is exciting, unique and worth reading. Give it a go!”
~ Zoltan Istvan, author of The Transhumanist Wager

“Overmind explores artificial intelligence, human agency, and an unsettling possibility about our universe. An engaging read with ideas that stayed with me after the final page.”
~ Wei Chen, Ph.D. Professor, OPIM & Generative AI at the University of Connecticut and author of The Owner: A Business Novel about Work in the GenAI Era
