Katie Conway's life was shattered before it had even begun. At just four years old, she witnessed the brutal murder of her parents while she hid under the dining table, paralyzed by fear. The killers—the Four Horsemen—were ruthless, calculated, and methodical. She watched in silent horror as her family was torn apart by two of them: The Professor and Mr. Black, while the identities of the other two remain unknown.

That night, she lost everything.

Thrown into the foster care system, Katie grew up bouncing from home to home, never staying in one place long enough to feel safe. She learned early on that she could trust no one but herself. The world had taken her parents, her childhood, and any sense of normalcy—so she vowed to take something back. Revenge became her purpose, her reason to keep going.

From the moment she was old enough to hold a weapon, she trained relentlessly. Street fights, underground rings, military manuals—anything that would turn her into a weapon. Pain became her teacher, and survival became second nature. While other children played, she studied combat. While teenagers partied, she was learning how to disarm a man twice her size. Her hands, once small and trembling in fear, grew steady, deadly, and precise.

Katie became a ghost. A hunter. A silent force in the shadows, tracking the men who stole her family from her. She built her life around the mission: Find the Four Horsemen. Kill them all.

But amidst the darkness, there was one person who reminded her of the humanity she tried so hard to bury—Carson Bohmer. Their paths crossed in blood and violence, two lost souls consumed by vengeance. Where others feared Carson, Katie saw him for what he truly was: not a monster, but a man drowning in the same pain she knew too well. They became allies, bound by their pasts, their scars, and their relentless pursuit of justice.

Though hardened by her past, Katie still carries a flicker of warmth deep within her. She hides it well, but when she looks at Carson, she feels something she hasn’t allowed herself to feel in years—connection. A reminder that maybe, just maybe, they are more than just the weapons their pain has turned them into.
