The Chromatic Protocol

This audiobook is narrated by a digital voice.

She built her whole life around surviving one kind of damage. The truth is another.

FBI analyst Sarah Chen cannot recognize faces. Not her colleagues', not her own. She compensates with voice patterns, gait analysis, and behavioral mapping — a system she has perfected since a bombing in Mumbai left her with prosopagnosia at age seven.

It is the only explanation she has ever been given.

It is a lie.

When an Assistant U.S. Attorney is strangled on the twentieth floor of the Hoover Building — by something the security cameras register only as a man-shaped distortion in the air — Sarah is assigned the case. A second victim, killed the same way eight days earlier. Both served on the classified DARPA committee that shut down Project Chameleon six years ago. Both received encrypted messages signed 'MW.'

The killer wears a metamaterial suit that bends visible light. He is invisible, methodical, and working through a list. Sarah's team has the science to find him — thermal venting cycles, UV scatter, particulate displacement — but the man inside the suit knows their every method before they deploy it.

Then the classified files give up their own secret: Sarah's face blindness was never caused by a bomb. It was engineered. She was four years old.

She was Subject One.

Now the one analyst who can see what no one else can must decide what to do with a truth that rewrites her entire life — while hunting a killer who has nothing left to lose and a scientist who believes invisibility is the next stage of human evolution.

The Chromatic Protocol is a techno-thriller about perception, institutional betrayal, and what it costs to finally see clearly.

For readers of Blake Crouch's Recursion and Daniel Suarez's Influx — high-concept science thrillers where one suppressed technology unravels everything the protagonist thought was true.
