What if the system designed to protect you is the very thing that takes something from you?

In the mountain town of Blackwood Falls, software engineer Julian Vance has built ARCHANGEL—a powerful predictive surveillance network designed to watch over every street, every door, and every movement. It was created to keep people safe.

Then his wife, Clara, disappears from a locked room while the cameras insist that she never left.

Desperate to understand what happened, Julian follows a trail of impossible footage, corrupted memories, hidden rooms, and secrets buried inside Blackwood Manor—the ancestral house he has spent years avoiding. As the boundaries between recorded reality, human memory, and artificial intelligence begin to blur, Julian discovers that ARCHANGEL may know more about Clara's disappearance than he does.

But every answer raises a more disturbing question:

If a machine can predict a person, remember a person, and recreate the way a person behaves—where does the human being end, and the algorithm begin?

The Shadow Algorithm is a gripping techno-thriller about surveillance, memory, artificial intelligence, love, and the unsettling space between what we remember and what may actually be true.
