A timely collection of rarely seen work by the world's most important war photographer - his first book in two decades.

James Nachtwey has devoted himself to documenting conflict and critical social issues, creating a much-admired body of work that covers events in conflict-riven countries and the theatres of war around the globe. This, his latest book, which accompanies a major exhibition, presents some of the most searing of his images, showing the ways in which he uses his camera to pay homage to the victims of violence.
