Mona Simpson is the author of five novels, including her latest, My Hollywood (Vintage Contemporaries, 2011), in which she examines the complexity, and also the currency, of raising a child. In it, Simpson, who believes that novels are “explorations of how to live,” revisits and elevates an important but often-unsung familial lynchpin, the domestic worker, and the overlapping, often-conflicting allegiances between parents, children, and “the help.”
