A missing woman vanishes on Bell Rock.
The only clue she leaves behind is a signal that can make people obey.
When search-and-rescue specialist Cass Whitaker reaches the red stone trails outside Sedona, she expects heat, panic, and bad terrain. She doesn't expect a disappearance that leaves no tracks, no body, and no explanation that makes sense.
Mara Koenig is gone. Her terrified friend is alive, but fractured by what she heard in the canyon. A strange tone moved through the rocks. A voice called from somewhere it shouldn't have been. Then the mountain answered.
Cass has spent her career trusting evidence, maps, and physical facts. But the deeper she digs, the less the case behaves like a rescue. Hidden chambers. Carved symbols. A buried transmission system. A cult waiting for the right night. And a government program called ARGUS that knows far more than it admits.
The signal is not just sound.
It can disorient. It can command. It can erase memory. It can turn faith, fear, and obedience into weapons.
As Cass joins forces with engineer Gabe Rourke, security chief Talley, and federal commander Priya Bhandari, the investigation moves from missing-person case to containment crisis. The threat is spreading through phones, radios, emergency channels, and anything else that can carry a pulse. Every test costs time. Every delay gives the people behind it another chance to finish what they started.
And the cult beneath the red rock isn't improvising.
They've been preparing for years.
They have names, targets, rituals, and a system built to reach thousands. They believe the signal is sacred. They believe Cass is standing in the way of revelation. And when the final transmission begins, everyone near Sedona becomes part of the experiment.
Cass has one chance to shut it down before the desert becomes a broadcast tower.
But stopping the signal may mean walking straight into the place where it was born.
Obsidian Creed is a tense supernatural techno-thriller about missing people, weaponized belief, government secrets, and the terrifying power of a voice no one can ignore.
Perfect for readers who enjoy:
- Supernatural suspense with a technological edge
- Desert-set thrillers filled with atmosphere and danger
- Ancient symbols, hidden chambers, and cult conspiracy
- Strong female protagonists under extreme pressure
- Government containment, signal warfare, and psychological threat
- Fast-paced mystery with horror tension and a cinematic climax
In the red rock silence, the signal is already waiting.
And once it knows your name, it doesn't let go.
