A Signal in the Noise: You Only Thought Were Control Techno Thriller

What if you could change someone's mind without them ever knowing? Marcus Chen is a self-taught programmer with a dead-end call center job and a secret: he's embedded mind control technology into noise cancellation software used by millions. It was supposed to stay hidden. A proof of concept for his personal interest. Something he'd never actually use. Then Judith Palmer - his high school crush who got him hired - asks for help. Her boss is harassing her, threatening her career. Marcus reveals his secret, thinking he can protect her. Thinking they'll use it once and walk away. They don't walk away. What starts as protection becomes power. What begins as justice becomes control. And as Marcus and Judith target more people - stalkers, abusers, politicians, anyone in their way - they become the very thing they set out to stop. Now Marcus is bleeding in his apartment, his laptop stolen, locked out of the kill switch that could end this. The person he loved has the weapon. And she's just getting started. Some power corrupts. Some power destroys. And some power should never exist in the first place.
