The Obsidian Signal: A Sci-Fi Horror Novel

By P.D. Thompson

The signal isn't a message. It's a parasite of the mind.

Dr. Edith Calloway, a disgraced cognitive scientist, is forced to return to Shadow Point-a clandestine facility where the walls hum with secrets and reality itself is a variable. Her mission: analyze the Obsidian Signal, an impossible frequency that is rewriting the minds of everyone who hears it.

Trapped with a small team in the facility's deepest levels, Calloway discovers the signal isn't just a broadcast. It's an intelligence.It shows you memories of lives you've never lived.It alters the past, one thought at a time.It learns from your fears, turning perception into a prison.
As the facility begins to twist into a non-Euclidean nightmare and her colleagues descend into paranoia, Calloway realizes the horrifying truth. The signal isn't just studying them. It's studying her.

But how do you fight an enemy that can rewrite the battles you've already lost? In a place where escape is just another part of the experiment, the only thing more terrifying than the signal... is what it's about to become.

Fusing the mind-bending science of Blake Crouch, the existential paranoia of Philip K. Dick, and the creeping cosmic horror of Jeff VanderMeer, The Obsidian Signal is a relentless descent into the dark heart of reality itself.
