The year is 2030. AI has made technology leapfrog into an age of deepfakes, drone swarms, and blurred borders. In such a world, war is no longer declared - it is designed. And sometimes, it unfolds in silence.For the first time in a hundred years, India's enemies are blind, its allies are silent, and its elite warriors have one impossible shot: a 20-hour mission that comes only once in a lifetime.Once in a Lifetime is a story that may never be acknowledged, involving people who may never be named, and a mission the world must never confirm. It imagines a future that feels alarmingly close, where diplomacy, espionage, and military precision intersect on a global chessboard tilted by misinformation and tech supremacy.At its core, this novella explores one powerful idea: The most important battles are not fought in daylight - they are engineered in shadows.India, facing existential threat and global indifference, activates Operation Trishul - a covert, coordinated response across continents and disciplines. From desert patrols to orbital interference, from fragile alliances to acts of quiet defiance, this is the story of those who act decisively when history pauses to take a breath.You will meet warriors who hide behind silence, diplomats who weaponize smiles, and scientists who must betray their ethics to serve their nation - just this once.This book is for readers who believe that courage comes in many forms - and not all heroes need medals.
