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 theater of war in the twenty-first century, has shaped her life. What she does, with clarity, beauty, and candor, is to document, often in their most extreme moments, the complex lives of others. It’s her work, but it’s much more than that: it’s her singular calling.  As a woman photojournalist determined to be taken as seriously as her male peers, Addario fights her way into a boys’ club of a profession. Rather than choose between her personal life and her career, Addario learns to strike a necessary balance. In the man who will become her husband, she finds at last a real love to complement her work, not take away from it, and as a new mother, she gains an all the more intensely personal understanding of the fragility of life.
