What if your smartwatch, grocery card, and gym membership were quietly building a profile that decides whether you live... or become spare parts?In a world where longevity billionaires can buy extra decades, a secret allocation centre mines global health data to pinpoint "perfect tissue" unwitting donors, then feeds their details to a black-ops organ market. People don't just die. They disappear. Families vanish from the map. Accidents are engineered. Bodies are stripped for parts.When Mara, a data scientist inside the system, realises healthy non-donors are being selected for "optimisation," she fakes her own death and runs, pregnant, hunted, and carrying the evidence that could burn the whole machine down. Every step she takes is logged somewhere. Every heartbeat is a data point. And the agency sent to erase her knows exactly how to make a disappearance look routine.If you love dark, near-future thrillers about weaponised tech, organ trafficking, and the courage to fight a system that sees you as inventory, this book is for you.
