Antonia Shimerdas moves to the harsh Nebraska heartland with her impoverished Bohemian family when she is still a girl. For young Jim Burden, who lives with his grandparents on a homestead nearby, Antonia is an embodiment of the female pioneer-self-sufficient, vigorous, and determined to withstand the daily challenges of maintaining home and family in a primitive countryside. When Jim grows up, his memories return to Antonia. In his effort to understand what she meant to him, he creates an enduring picture of the American frontier and of a woman of unusual spirit.
