All Systems Listening: A Techno-Thriller of Surveillance, Betrayal, and Hidden Control

by Debora Early

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.

About the author

Debora Early writes pulse-pounding techno-thriller romances where cutting-edge science collides with high-stakes danger—and where trust can be as risky as the truth. Blending Silicon Valley intrigue, shadowy conspiracies, and emotionally charged slow-burn tension, her stories explore what happens when the future arrives faster than morality can keep up. When she’s not crafting tales of rogue algorithms, forbidden alliances, and secrets buried deep in the dark corners of power, Debora can be found researching emerging technology, sipping strong coffee, and imagining the next impossible choice her characters will have to survive.

Reviews

[Kimberley Mileski]

This was a good book! Luckily, I worked in IT and consider myself a bit of a "tech head". I think someone with no technical background may not understand large portions of this book. But for those that understand the technical side of IT, it was a good book. I felt like it had a bit of a slow start but by the end, I kept reading to try and see how it finished.

The story was good, the writing annoying (lots of repetition, brand names filling the pages) and if you are not in cybersecurity or IT, a lot of the technical stuff may take away from the pace of the novel. Probable story.

I won this book from a Goodreads Giveaway. I enjoyed this book. It was very detailed and descriptive.
