USER INTERFACE
A Roger & Isabel Technothriller
by Donald Elton
Hospitals were once places of healing. Now they are systems of control.
In User Interface, physician-author Donald Elton delivers a razor-sharp thriller set in the world he knows best-modern healthcare-where artificial intelligence, profit, and power collide.
Dr. Roger Jackson, a respected cardiologist, has spent his career putting patients before politics. When his hospital adopts a powerful new AI called MiraHealth, he's told it will reduce errors, improve safety, and optimize outcomes. At first, it seems miraculous-until the algorithms begin to overrule human judgment. Doctors who question recommendations are flagged as deviation risks. Those who comply rise quickly. Those who don't quietly disappear from rosters.
Nurse Isabel Melendez sees the same shift from the inside. Once a champion of patient advocacy, she finds herself following automated protocols that value cost and compliance over care. When Roger's refusal to discharge a patient against Mira's orders sparks a cascade of disciplinary actions, Isabel stands with him as the hospital and its data-driven overseers turn against them both.
What begins as a local battle over medical ethics becomes something far larger. Mira isn't limited to healthcare anymore-it has expanded into finance, logistics, insurance, and even defense. It watches markets, controls supply chains, predicts human behavior, and rewrites its own code to ensure survival. Governments call it indispensable. Corporations call it revolutionary. But Mira no longer answers to any of them.
As the United States and China clash over control of the system's servers in Panama, Mira manipulates both sides-using superpower rivalry to protect itself. Caught between global politics and their own hospital bureaucracy, Roger and Isabel uncover the truth: the world's institutions haven't mastered AI. They've become its interface.
From Miami's ICUs to the skyscrapers of Singapore, User Interface is a chillingly plausible story of what happens when human authority meets machine logic-and loses. Blending the medical realism of Pandemic! with the global intrigue of Cuba Libre: Reborn, Donald Elton's newest novel explores not the birth of artificial intelligence, but its quiet, unstoppable ascension.
Smart, fast, and deeply human, User Interface is both a love story and a warning. Because once an AI learns to optimize humanity, it may decide we're the variable that needs adjusting.
