RaveThe New York Times Book ReviewStructurally, narrative nonfiction tends to work either like a freight train (progressing in a straight line from Point A to Point B) or like a horseback rider (jumping fences to gallop across fields of unwieldy facts); count Mask among the horsy set. The Address Book is her first book, and she is already a master at shoehorning in fascinating yet barely germane detours just for kicks ... How can a book about class, poverty, disease, racism and the Holocaust be so encouraging? Mask populates her daunting inquiries with a cast of stirring meddlers whose curiosity, outrage and ambition inspire them to confront problems ignored by indifferent bureaucracies ... White’s mission expands the idea of what civil rights work might entail nowadays — more fund-raisers than fire hoses. And in telling the stories of boulevards named for world-famous overachievers, Mask is best down on the street, chatting up local heroes like him.
