An astonishing book-length poem in seven parts from the winner of the Pulitzer Prize and the National Book Award. With piercing clarity and craftsmanship, Mary Oliver has fashioned an unforgettable poem of questioning and discovery, about what is observable and what is not, about what passes and what persists. "It's hard to imagine anyone putting down Oliver's book-length poem and not sighing with satisfaction, so sensible is every word and thought." — Virginia Quarterly Review
