Book Description
Long-haul trucker Garth Heller has spent years chasing one goal: owning a truck he can finally call his own.
But buried deep within its engine is an ancient evil, waiting for someone willing to turn the key.
What begins as the fulfillment of a lifelong dream soon becomes something far more terrifying. As the truck's influence grows, Garth begins losing pieces of himself until the man behind the wheel is no longer the one making the decisions.
He wakes with blood on his hands and stretches of highway he can't remember driving.
Somewhere along those missing miles, innocent people are dying—and Garth has no way of knowing whether he's the killer or just another victim.
And the Peterbilt's run is far from over. Somewhere out on the open road, it's only a matter of time before someone else climbs behind the wheel.
Blending occult mythology with psychological terror, The Obsidian Rig delivers the creeping dread of Stephen King's Christine with the relentless tension of The Thing.
For now, the answer lies somewhere beyond the next mile marker.

Reader Profile & Best Moment to Read
Read The Obsidian Rig when you’re craving dark, fast-moving supernatural horror that makes the open highway feel dangerous. It’s a strong pick for fans of cursed objects, possessed vehicles, occult mythology, and psychological terror, especially stories where an ordinary person slowly loses control of his own mind and actions. Expect a violent, unsettling ride that may have you looking twice at the next black semi coming up behind you.
Themes, Ideas & Atmosphere
The book is defined by possession and loss of control, as the Peterbilt gradually consumes the identities of those who drive it; cursed-object horror, with a seemingly perfect truck serving as the vessel for an ancient malevolent entity; corruption through human weakness, as the entity exploits pride, addiction, anger, fear, and desire; and evil that survives its victims, allowing the threat to continue as the truck passes from one owner to the next. The tone is violent, ominous, and relentless, combining psychological horror, occult mythology, and road-thriller tension.
If You Loved These, You'll Love This
Christine by Stephen King is the clearest comparison for its seductive, seemingly alive vehicle that corrupts the person behind the wheel. The Thing fits the book’s sense of an ancient, malevolent force that can consume human identity and make it difficult to know where the person ends and the monster begins. And Duel by Richard Matheson adds the relentless highway menace, where a massive truck transforms the open road into a place of isolation, pursuit, and dread.
The Story Behind the Book
After more than fifty years as a professional truck driver, Earl D. Coobs didn’t have to imagine the isolation of empty highways, lonely truck stops, or headlights appearing in the distance after midnight. Those millions of miles gave him the firsthand experience behind The Obsidian Rig and inspired its central idea: take the familiar world of long-haul trucking and change one small thing until an ordinary stretch of road becomes something terrifying.
The Central Question
At its heart, The Obsidian Rig asks what happens when something you’ve worked your whole life to possess begins possessing you instead. Garth’s dream truck gradually steals his control, his memories, and his sense of who he is, leaving him caught between perpetrator and victim. The story is meant to leave readers thinking about how easily desire can become obsession, how vulnerable we are when control slips away, and whether evil can ever truly be destroyed or simply finds someone new to carry it forward.
