What if the war between Heaven and Hell wasn’t happening in some distant realm—but right here in our cities? Dive into the world of Urban Fantasy.
In Diary of a Demon Hunter, readers step into the dangerous and unforgiving world of Jack Thorn, a man who hunts demons hiding in plain sight. Jack isn’t a shining hero or a chosen savior. He’s a professional survivor—scarred by years of violence, driven by grim experience, and fully aware that every hunt could easily be his last.
Most people move through their lives without noticing when something is wrong. They walk past strange shadows, brush off uneasy feelings, and ignore the small moments that don’t quite make sense. A person who suddenly seems different. A room that feels colder than it should. A quiet street where the air itself feels… off.
But Jack Thorn knows better.
He’s spent years tracking the creatures that slip into the human world unnoticed. Demons don’t arrive with horns and fire. They arrive quietly. They wear human faces, whisper into broken minds, and wait for the right moment to turn ordinary lives into something violent and irreversible.
Jack’s job is to stop them before anyone realizes what was really happening.
Through a series of personal diary entries, Jack records the hunts that define his life. Each entry reveals another encounter with the supernatural world hiding beneath the surface of the city—possessions that spiral into bloodshed, creatures that stalk the night, and horrors that most people would refuse to believe even if they saw them with their own eyes.
But the deeper Jack digs, the clearer it becomes that the demons he’s been hunting are only part of the story.
The attacks are becoming more frequent. Possessions are spreading faster. Entire parts of the city seem to shift in ways that shouldn’t be possible. It begins to feel less like random chaos and more like preparation.
And if someone—or something—is preparing the city for what comes next, Jack might already be standing in the middle of a much larger war.
As his diary fills with new entries, brutal encounters, and close calls that nearly cost him his life, Jack starts uncovering clues that point toward a hidden conflict stretching far beyond the streets he patrols. Forces from both Heaven and Hell are moving pieces into place, and humanity may simply be the territory they intend to fight over.
Caught between powers far greater than himself, Jack has only one option left: keep hunting.
Because if the demons succeed in establishing their foothold here, the city won’t just become dangerous.
It will become the first battlefield in a war that could consume the entire world.
Preview Excerpt
My name is Jack Thorn.
I hunt demons.
Most people never notice when the world starts to go wrong. They keep walking, keep talking, keep living their lives while something impossible slips quietly into the cracks around them.
But once you’ve seen it—once you’ve watched something wearing a human face tear a room apart—you can’t pretend anymore.
That’s when the job starts.
The first rule of demon hunting is simple: if something feels wrong, it probably is.
The second rule is worse.
By the time you realize what you’re dealing with… it’s already too late.
