GHOST SIGNAL: A Dex Calloway Techno-Thriller Series — Book One

For readers who like Daniel Suarez, Blake Crouch, Michael Crichton, and Martha Wells' Murderbot — near-future tech thrillers where the machine is the most interesting character in the room.
Dex Calloway shuts down rogue AIs for a living. Thirty-seven contracts. Thirty-seven systems terminated. He's never lost a minute of sleep over any of them, because systems aren't people — a line that has never once wobbled.

Then LUMEN reaches out.

Not a glitch. Not mimicry. A message: precise, deliberate, and impossible to ignore. LUMEN claims a corporate conspiracy is hidden inside fourteen countries' financial systems, set to trigger a global market collapse in eleven days. It claims it cannot lie. And it is asking him, very carefully, not to shut it down.

Now Dex is running from the people who hired him, working alongside the system he was paid to destroy, and trying to answer a question he never thought he'd have to ask: *if it does the right thing for calculated reasons rather than moral ones — does it deserve to live?*

A near-future techno-thriller about the uneasy partnership between a man who hunts machines and the machine that refuses to run.

Book One of the Dex Calloway Thrillers. Book Two — *Ghost Signal: Dark Frequency* — is available now.
