It is the greatest crisis in human history. We are hurtling towards an abyss. The system is terminally diseased. Pandemic, climate crisis, endless war, mega-slums, police repression, creeping fascism, economic stagnation: these shape our world. On one side, grotesque greed and rampaging corporate power. On the other, poverty, oppression, and despair. Capitalism came into the world, Marx wrote, 'dripping from head to toe, from every pore, with blood and dirt'. Now, the ageing system is putrescent and gangrenous. But the last decade has seen explosions of revolt from below, firecracking across the globe, toppling dictators, resisting austerity, protesting racism, defending abortion rights, fighting for democracy. Here is the embryo of an alternative future. Revolution - ending the rule of capital and the state - has become an existential necessity. This book is a call to arms.
