O Pioneers! was Willa Cather's first great novel and to many it remains her unchallenged masterpiece. No other work of fiction so faithfully conveys both the sharp physical realities and the mythic sweep of the transformation of the American frontier and the transformation of the people who settled it. Cather's heroine is Alexandra Bergson who arrives on the wind-blasted prairie of Hanover Nebraska as a girl and grows up to make it a prosperous farm. But this archetypal success story is darkened by loss and Alexandra's devotion to the land may come at the cost of love itself.
