He’s a soldier without a war, guiding tourists through a world with no consequences. But a new mission is about to drag him into a battle for survival against a legend that should not exist.

Kyle Rennick, a former Army Ranger haunted by the ghosts of his past, is sleepwalking through life as a wilderness guide for wealthy clients . Each day is a soul-crushing reminder of the man he used to be, a warrior trapped in a world of packaged adventure and thousand-dollar hiking boots.

A lucrative offer to guide a mysterious archaeological expedition into a forbidden Arizona canyon promises a chance to feel alive again . The goal: to find proof of an ancient Native American legend the world has forgotten.

But the deeper they venture into the labyrinth of stone, the more the canyon resists. Their equipment malfunctions. They are stalked by something immense and unseen. And the story carved into the ancient rock walls is not just a myth—it’s a warning .

When strange signals in the dark escalate into acts of impossible violence, Kyle realizes this is no ordinary mission . They have trespassed into the sacred territory of a creature of unimaginable power. Trapped by a catastrophic flash flood and hunted by a force of nature, Kyle must become the soldier he once was to get his team out alive .

But in the Canyon of the Lost Echoes, survival is only the beginning. The real battle is for your belief in reality itself.
