The Shadow Frequency

Rate this book
When machines start to whisper, one man hears the truth.

Jimmy Puckett, a Tennessee automation engineer, thinks he’s found a simple data glitch inside an industrial control system. But when the same strange signal appears across multiple networks, people connected to it begin disappearing. At 3:07 a.m. every night, the same encrypted pulse returns—stronger, spreading, alive.

As federal agents close in and shadow contractors hunt him across the South, Jimmy uncovers a hidden communication buried in the power grid. Someone—or something—is using industrial systems to talk. The message isn’t random. It’s rewriting everything it touches.

Now he’s the only person who can stop it, but the code recognizes his name. What began as a signal becomes a chase across Tennessee, Washington D.C., and the open sea, where the final node waits to awaken.

In a world built on automation, what happens when the automation starts fighting back?

The Shadow Frequency is a gripping, high-voltage thriller that blends technology, conspiracy, and survival into a story of one man caught between the human world and the digital one that’s learning to live without us.
