Beyond race or class, our lives are defined by a powerful, unspoken system of divisions. In Caste, Pulitzer Prize-winning author Isabel Wilkerson gives an astounding portrait of this hidden phenomenon. Linking America, India, and Nazi Germany, Wilkerson reveals how our world has been shaped by caste - and how its rigid, arbitrary hierarchies still divide us today.

With clear-sighted rigor, Wilkerson unearths the eight pillars that connect caste systems across civilizations and demonstrates how our own era of intensifying conflict and upheaval has arisen as a consequence of caste. Weaving in stories of real people, she shows how its insidious undertow emerges every day; she documents its surprising health costs, and she explores its effects on culture and politics. Finally, Wilkerson points forward to the ways we can - and must - move beyond its artificial divisions, towards our common humanity.

Beautifully written and deeply original, Caste is an eye-opening examination of what lies beneath the surface of ordinary lives. No one can afford to ignore the moral clarity of its insights, or its urgent call for a freer, fairer world.
