Echoes of the Dark

(This book is a dark horror thriller mystery novel. The traces are clearly visible, where they can be seen.) When the price of saving the world is turning yourself into a monster—do you still dare to move forward? Oktas's answer: Everything. A brutal ritual buries the "Seed of Residual Echoes" inside him. He becomes a half-demon capable of devouring demons and evolving—but also a living tragedy whose humanity fractures a little more every time he uses his power. From that moment on, he is no longer an ordinary person. He is the one forced to settle the world's debts—walking the line between monster and man. From the paranormal scams on the fringes of Sanfronis City to the hidden war sweeping the globe, Oktas hunts demons and loses pieces of himself along the way. He has betrayed trust, buried bodies with his own hands, and pushed himself deeper into the darkness time and time again. The more truth he uncovers, the heavier the price he pays. Because in this world—power, choice, survival—nothing comes free. This is not a simple adventure. This is a story about truth, silence, costs, and decay. What's truly terrifying here is not the monsters. It's that in a world full of lies, the one who tells the truth will always be the first to be ground down by the world.
