In a world where a single glance can kill, humanity faces its deadliest adversary yet. The Smile isn't just a curse—it's an intelligent, evolving predator that spreads through attention, reflection, and even thought. What begins in the abandoned halls of Saint Helena Hospital escalates into a global nightmare, as cities fall into chaos and survivors fight to stay human. Lívia and a band of desperate fighters navigate a city alive with sinister grins, where mirrors, screens, and shadows are deadly. Every blink could mean death—or worse. As the Smile adapts faster than they can react, they must outsmart a force that anticipates their every move. The world holds its breath. Every reflection is a trap. Every face could be the last you see. Survival is temporary. Trust is a liability. And the Smile… is always learning. Can humanity survive the last blink—or will the world smile forever?
