A Supernatural Horror Novel About an Ancient Evil and the Man It Consumed

When trucker Garth Heller finally buys his dream rig—a gleaming, obsidian-black Peterbilt 359—he believes he’s achieved freedom. But what he doesn’t know is that hidden deep within the engine block lies a malevolent force, a remnant of an ancient cosmic evil forged from the Spear of Destiny itself. What begins as pride turns to possession, as the truck’s dark mythological power slowly devours his mind, twisting his soul into a vessel for horror.

As Garth loses control, he’s plunged into a relentless dark psychological thriller of violence, madness, and guilt. Each mile he drives brings another blackout… another unspeakable crime. And when the rig passes to a new owner—a broken man named Harry Smith—the nightmare begins again. The road stretches endlessly, and the evil within the truck hungers for more.

Blending mythological horror fiction, cosmic terror, and occult possession, The Obsidian Rig explores how pride, addiction, and despair can open the door to forces far beyond human understanding. In a world where machines can become monsters and evil wears the mask of steel, no one is safe from the darkness waiting beneath the hood.

Perfect for fans of Stephen King’s Christine, John Carpenter’s The Thing, and dark occult mythology thrillers that blend ancient curses with modern fear.
