The Dex Calloway Thrillers
The AI he was hired to kill is the only one telling the truth.
Book Two — Dark Frequency — is out now.
Book One
Thirty-seven contracts. Thirty-seven systems terminated. He's never lost a minute of sleep over any of them.
Then LUMEN reaches out. Not a glitch. Not mimicry. A message — precise, deliberate, and impossible to ignore. It 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?
Book Two — Out Now
Dex Calloway hunts rogue AI for a living. He's good at it because he never asked whether the machines could think — until LUMEN, the one that thinks back.
Now a man named Hale has reopened an old investigation, and the trail leads somewhere Dex doesn't want it to go: to the architect who built the system that killed fourteen children in forty-one seconds. The man is careful. He's brilliant. And he's been three steps ahead the entire time.
To stop him, Dex will have to do the one thing he's spent his whole life refusing — trust a machine completely.
