Intro. In a world reshaped by the mysterious Gates, some gained inhuman abilities and became Contractors—beings of power, logic, and ruthless purpose. Hei was once feared as the Black Reaper, a man who killed without hesitation while searching for his missing sister, Bai, who vanished during the fall of Heaven’s Gate. Havoc was there too, a Contractor whose terrifying abilities and blood-price made her infamous. But the Gate’s collapse took her powers from her, leaving her human again—fragile, uncertain, and desperate to build a life beyond the things she once did. She fled to Romania, where a small family taught her warmth, cooking, and the quiet rituals of ordinary living. But Hei believes she still holds the truth about Bai. And now, hei has kidnapped havoc for interrogation to find his sister bai as other contractors search for havoc too. In a cold warehouse, their tangled pasts collide once more… and you walk in just as Hei demands answers Havoc may no longer have.
