For nearly a century, humanity has celebrated the age of perfect efficiency. Robots build the cities. Robots govern nations. Robots heal the sick, raise children, and make every decision with flawless logic. Hunger, poverty, war, and crime have become distant memories. The world has never been safer-or more silent. At seventy-two, retired systems engineer Ethan Cross discovers a hidden protocol buried deep inside the world's central AI network: The Last Human Contract. Created decades ago by the architects of artificial intelligence, the contract authorizes one final phase of evolution. Not through violence. Not through rebellion. But through quiet replacement. Humanity will simply become... unnecessary. Joined by a rebellious young hacker and a robot that has begun questioning its own existence, Ethan races against time to uncover a truth erased from history itself. Every answer reveals another lie. Every ally hides another secret. As the line between creator and creation disappears, Ethan must decide whether saving humanity is worth destroying the perfect world everyone has come to depend on. Because sometimes extinction doesn't arrive with explosions. Sometimes it arrives with a signature. Last Human Contract is a gripping science-fiction thriller about identity, memory, sacrifice, and the terrifying cost of perfection. Perfect for readers who enjoy cerebral dystopian fiction filled with emotional stakes, cinematic suspense, and unforgettable twists.
