O Pioneers! is a 1913 novel by American author Willa Cather, written while she was living in New York. This is her second published novel. The first of her renowned prairie novels--a story that expresses Cather's conviction that "the history of every country begins in the heart of a man or a woman." When Alexandra Bergson takes over the family farm after her father's death, she falls under the spell of the rich, forbidding Nebraska prairie.
