Singapore, 2061. An engineered virus has torn through the city, turning the infected into silent hunters guided by corrupted nanotech targeting neural implants everyone carries. Damian Kael Caine wakes up on day 143. Former soldier. Five months in a coma. Broken memories, a body that barely remembers how to stand. He doesn't remember faces or names. Just that the people he loves are out there somewhere. Waiting for him is THEO-3, a robot built by his grandfather. Programmed never to harm anyone, he's spent 142 days alone making porridge and waiting with an optimism that has no business existing in an apocalypse. Together, with a dog they find along the way, they move through the ruins of a city designed to be impossible to leave, searching for a family Damian can feel but cannot remember. The virus wasn't an accident. Someone made it deliberately. And Damian is going to find out who.
