Felix Martin. Money: The Unauthorized Biography (Alfred A Knopf, 2014).
"What is money, and how does it work? In this tour de force of political, cultural, and economic history, Felix Martin challenges nothing less than our conventional understanding of money. He describes how the Western idea of money emerged from interactions between Mesopotamia and ancient Greece and was shaped over the centuries by tensions between sovereigns and the emerging middle classes. He explores the extraordinary diversity of the world's monetary systems, from the Pacific island of Yap, where value was once measured by immovable stones, to the currency of today that exists solely on globally connected computer screens."
