The poet Jorie Graham is one of our great literary mappers of everything, everywhere all at once. As James Longenbach put it, she engages “the whole human contraption . . . rather than the narrow emotional slice of it most often reserved for poems.” Graham is a chronicler of bigness, the overawing bigness of our planet but also the too-bigness, at times, of the self. “I am huge,” she writes mournfully, in “Prayer Found Under Floorboard,” an elegy for what humans have already blotted out.
