The book guides us to know Dorothy Day, indicated as an example by Pope Francis; American journalist and founder with Peter Maurin of The Catholic Worker movement. A revolutionary woman with an adventurous, uncomfortable, difficult life and a disconcerting topicality between inequalities, poverty, work, ecology, motherhood (and rejection of it), pacifism, absolute faith and a difficult relationship with the Catholic Church. Following her, we meet Margaret Sanger, Eugene O'Neill, Jacques Maritain, Martin Luther King, Joan Baez, Thomas Merton, Fidel Castro, Ignazio Silone, Teresa of Calcutta, Communists and Popes, fear of flying and American prisons, homeless people unapproachable by their smell, mothers who lose their wits seeing their children die of hunger, trampled farmers, annihilated unemployed who arrive at breakfast brandishing knives. Because Dorothy Day did not only welcome the last of America, she did not only dedicate her existence to them, but she lived her life with them. In the same houses, at the same table, in the same bathrooms, with the same clothes.
