In the introduction to his book, Savage Continent, Keith Lowe writes:
Imagine a world without institutions. No governments. No school or universities. No access to any information. No banks. Money no longer has any worth. There are no shops, because no one has anything to sell. Law and order are virtually non-existent because there is no police force and no judiciary. Men with weapons roam the streets taking what they want. Women of all classes and ages prostitute themselves for food and protection.
This is not the beginning to a futuristic thriller, but a history of Europe in the years directly following World War II, when many European cities were in ruins, millions of people were displaced, and vengeance killings were common, as was rape.
