International bestselling author Roberto Saviano explores the inner workings of the world of drugs and dirty money - its rules and armies - and the true depth of its reach.In many countries, 'zero zero' or double zero flour is the finest, best flour on the market. Among narco-traffickers, then, 'zero zero zero' is the nickname for the very purest, highest quality grade of cocaine. From Mexican cartels to Milanese financiers, Guatemalan mercenaries to Ukrainian warlords, Calabrian traffickers to the traders in Wall Street and London who wash the money clean, this is an unforgettable story that goes around the globe and through every level of society to show the extent to which the drug trade affects us all.Weaving together stories, interviews, wiretaps and his own experience of the criminal underworld, Saviano reveals an international narco-state, which, in the wake of the financial crisis, is now the pillar of our global economy. It is the perfect synthesis of modern capitalism, where everything is for the taking - and all is consumed, ruined and destroyed. Dark, visceral and terrifying, this is a grand drama of power, blood and money. It is the story of our world.
