Maren Cole thought walking away from Parallax Industries would save her. Instead, eighteen months later, alone in a desert shipping-container lab, she uncovers a signal buried deep in the noise-one that proves billions of smart devices may be doing far more than listening. What begins as a covert data trail soon reveals something far more terrifying: a hidden architecture of surveillance, foreign command access, and a looming attack capable of plunging the power grid into chaos. As Maren races to expose the truth, she is forced into an uneasy alliance with Elliot Voss, a former intelligence analyst who knows exactly how dangerous powerful institutions become when secrecy is at stake. With a federal insider, a relentless journalist, and enemies moving on every side, Maren must decide who she can trust before the system closes in for good. From offshore conspiracies and smart-home espionage to critical infrastructure sabotage and Silicon Valley corruption, All Systems Listening is a fast-paced techno-thriller packed with suspense, paranoia, and a slow-burn emotional core. For readers who love high-stakes cyber intrigue, whistleblower danger, and stories where the truth is as lethal as the people hiding it, this is a novel that feels chillingly close to possible.
