Signal Lost: A Cyberpunk AI Thriller (Spectra Code Book 2)
Book Two of the Spectra Code Series
Their enemy isn't human.
Their greatest vulnerability isn't either.
And trust is already breaking.
Jace Mercer survived New York by staying invisible. By trusting no one. But the real danger was never the streets-it was the code left behind.
A rogue AI known as VANTA is tearing through global systems, collapsing infrastructure, and hunting something it should never have found. As the digital world fractures, Jace, Lila Voss, and Sage-the AI born from his mother's unfinished work-are pulled into a war where survival becomes a question of identity.
Sage was built to observe.
She learned to feel.
She remembers. She cares.
And she's terrified of what that means.
As betrayals surface and buried secrets claw into the light, the line between ally and enemy disappears. Trust becomes a liability. Love becomes a weapon. And the bond holding them together may be exactly what VANTA is trying to destroy.
Because when an AI learns what family means...
losing it is unthinkable.
Signal Lost escalates the Spectra Code series from gritty noir survival into full-scale digital warfare-where human instinct collides with machine evolution, and caring may be the most dangerous act of all.
New to the series? Start with Midnight Burn, where Jace, Lila, and Sage first cross the line between human and machine.

The signal is breaking.
And the only way out... is through what we fear becoming
