Book excerpt: War photographer Lynsey Addario's memoir It's What I Do is the story of how the relentless pursuit of truth, in virtually every major theatre of war in the twenty-first century, has shaped her life. Lynsey Addario was just finding her way as a photographer when September 11th changed the world. One of the few photojournalists with experience in Afghanistan, when she is asked to return and cover the American invasion, she makes a decision - not to stay home, not to lead a quiet or predictable life, but to set out across the world, face the chaos of crisis, and make a name for herself. Addario travels with purpose and bravery, photographing the Afghan people before and after the Taliban reign, the civilian casualties and misunderstood insurgents of the Iraq War, as well as the burned villages and countless dead in Darfur. She exposes a culture of violence against women in the Congo and tells the riveting story of her headline-making kidnapping by pro-Qaddafi forces in the Libyan civil war. As a woman photojournalist Addario is determined to be taken as seriously as her male peers. She fights her way into a boys' club of a profession; and once there, rather than choose between her personal life and her career, Addario learns to strike a necessary balance. Watching uprisings unfold and people fight to the death for their freedom, Addario understands she is documenting not only news but also the fate of society. It's What I Do is more than just a snapshot of life on the front lines; it bears witness to the human cost of war.
