A siege turns a city into a stomach. This book follows the universal progression of hunger: from orderly stores and ration math to substitutes, scavenging, and the slow collapse of what people are willing to call food. Organized by category and escalation, each chapter explains a stage of deprivation and punctuates it with documented stories from real sieges, told through letters, diaries, ration notices, and survivor accounts. The result is not a cookbook of horrors, but a history of thresholds: the moments when necessity rewrites morality.
