Marco Reyes was trained to erase people. For decades, he lived in the shadows—an elite hitman executing impossible missions for a hidden system designed to make corruption invisible. No attachments. No mercy. No past. When Marco is finally offered a way out—a clean disappearance and a new life—there is only one condition: one last job. Then he learns the truth. He is being hunted. The system he once served has turned on him. And the daughter he abandoned years ago is now the key to everything. Sofia Reyes is a fearless young journalist uncovering a conspiracy that reaches into governments, corporations, and private armies. What she doesn’t know is that her entire life was shaped by the same machine Marco helped build—and that her investigation has triggered a silent war. As father and daughter are forced together, they uncover a chilling reality: Sofia was never just a target. She was part of the design. With time running out and enemies closing in from every direction, Marco must return to the life he tried to escape—using violence not for profit, but for protection. Each choice drags him deeper into the past he hoped to bury, while Sofia is pushed to decide how much truth the world can survive. From the streets of Manila to international power corridors, FAULT LINE is a relentless crime thriller about systems built to control humanity—and the one thing they can never fully contain: choice. Stylish, emotionally charged, and brutally intelligent, FAULT LINE is a story of blood ties, moral reckoning, and a man who must become a father not by saving the world—but by refusing to let it erase his daughter. When the system breaks, blood chooses sides.
