Simone de Beauvoir famously wrote, 'One is not born, but rather becomes, a woman'. In this groundbreaking work of feminism she examines the limits of female freedom and explodes our deeply ingrained beliefs about femininity.

Drawing on sociology, anthropology and biology, The Second Sex is as important and relevant today as when it was first published in 1949. .
