Legendary poet, novelist, and essayist Margaret Atwood gives us a surprising look at the topic of debt -- a timely subject during our current period of economic upheaval, caused by the collapse of a system of interlocking debts. Atwood proposes that debt is like air -- something we take for granted until things go wrong. Payback is not a book about practical debt management or high finance, although it does touch upon these subjects. Rather, it is an investigation into the idea of debt as an ancient and central motif in religion, literature, and the structure of human societies. By investigating how debt has informed our thinking from preliterate times to the present day through the stories we tell each other, through our concepts of balance, revenge, and sin, and in the way we form our social relationships, Atwood shows that the idea of what we owe one another -- in other words, debt -- is built into the human imagination and is one of its most dynamic metaphors.
