In this unflinchingly honest and deeply moving memoir, the famously private author speaks out publicly for the first time about her work among the most desperate members of our society. She offers achingly acute portraits of the people she met along the way—and issues a heartfelt call for more effective action to aid this vast, deprived population. Determined to supply the homeless with the basic necessities to keep them alive, she ends up giving them something far more powerful: a voice.
