O Pioneers! is a 1913 novel by Willa Cather, the first novel of her Great Plains trilogy, followed by The Song of the Lark (1915) and My Ántonia (1918). It tells the story of the Bergsons, a family of Swedish-American immigrants in the farm country near the fictional town of Hanover, Nebraska, at the turn of the 20th century. The main character, Alexandra Bergson, inherits the family farmland when her father dies, and she devotes her life to making the farm a viable enterprise, despite others’ many pleas to leave for greener pastures.
