Killian Drex is a ghost. A highly trained operative, he exists in the shadows, his past a carefully constructed lie. But when fragments of a forgotten life-a life that isn't his-begin to surface, Killian's carefully controlled world shatters. He's not just an assassin; he's an Echo, a clone imprinted with the memories of a brilliant scientist named Caleb Drex, a man Genaris stole, fragmented, and used to create an army. Hunted by Europol agent Elira Voss, a woman relentlessly pursuing the truth behind her own brother's disappearance into Genaris's dark experiments, Killian discovers a horrifying reality: he is one of thousands, each a weapon, each a stolen soul. As his original consciousness fights to resurface, Killian and Elira are drawn into a desperate, globe-spanning race against a corporation that controls not just armies, but minds.From the opulent towers of Dubai to the frozen wastes of Antarctica, they unravel a conspiracy that aims to control humanity by isolating the very essence of the soul. But in their fight for freedom, Killian must confront the ultimate choice: destroy the very network that created him, even if it means erasing every echo of himself, or succumb to a monstrous power that promises omnipotence.
