In the frigid days of February 1870, Caroline Ingalls and her family leave the familiar comforts of the Big Woods of Wisconsin for a new life in Kansas Indian Territory. Packing what they can carry in their wagon, Caroline, her husband Charles, and their little girls, Mary and Laura, head west to settle in a beautiful, unpredictable land full of promise and peril. The pioneer life is a hard one, especially for a pregnant woman with no friends or kin to turn to for comfort or help. But Caroline's new world is also full of tender joys. In adapting to this strange new place and transforming a rough log house built by Charles' hands into a home, Caroline must draw on untapped wells of strength she does not know she possesses.
