The Devil In The Walls

The Devil in the Walls  A Novel by Ty A. PenrySera Voss has spent six years in emergency medicine learning to trust the body over the mind-vitals don't lie, even when people do. But when a rhythmic scraping wakes her at 2:14 a.m., something inside her apartment walls begins keeping its own kind of record. It breathes. It watches. And it knows her name. At first, Sera tries to explain it away-exhaustion, stress, the strange acoustics of an aging building.
But the phenomena follow her beyond her apartment: lights pulse with a resting heart rate, shadows stand upright in corners, and the pressure in the air drops with the unmistakable intent of something drawing near. Whatever is inside the walls isn't confined to them anymore. It's learning her routines. It's studying the people she loves. When her sister Mara becomes a target of its quiet attention, Sera realizes the presence isn't random, and it isn't finished.
It has been waiting-patiently, deliberately-and now that it has spoken her name, it wants something only she can give. As the boundary between the living world and whatever breathes behind the plaster thins, Sera must confront the truth she's spent her life avoiding: some threats can't be triaged, charted, or reasoned with. Some come for you because they already know who you are. And some don't stop at the walls.
