The Book of Mev is the story of Mev Puleo, an American photojournalist and young Catholic who actively confronted a world of injustice, poverty and violence. From witnessing homelessness in the United States to struggles for social change in Haiti, El Salvador, and Brazil, Puleo used photography and interviews to be a bridge between poverty and affluence, the First World and the Third World. Puleo's familiarity with suffering, however, was dramatically intensified when she was diagnosed with a malignant brain tumor at the age of thirty-one. She died twenty-one months later.
