Diplomatic Immunity

An alien ambassador arrives on Earth with an invitation humanity can't refuse: join his galaxy-spanning empire or face conquest. There's just one problem, he's functionally indestructible. Any weapon aimed at him transforms into the weapon itself. Any attack becomes its opposite. As nuclear bombs turn into butterflies and bullets become flowers, Colonel Cercy leads a team of scientists in a desperate attempt to neutralize this impossible visitor before Earth's surrender becomes official. What follows is a bewildering game of cat and mouse where every lethal strategy backfires, every solution fails, until they discover the ambassador's power stems from something far stranger than technology: pure chaos itself. The ending is as elegant as it is absurd. Robert Sheckley, the master of paranoid sci-fi comedy, delivers a novel that is as funny as it is unsettling, a farcical arms race that somehow also asks serious questions about authority, resistance, and what happens when human ingenuity meets something genuinely alien.
