It's 1845 in the bustling frontier town of Brookfield, Wisconsin. Five-year-old Caroline lives in a frame house at the edge of town with her mother, her grandmother, and her five brothers and sisters. Caroline's father was lost at sea the year before, and the close-knit family is struggling to cope without him. Each day brings Caroline new responsibilities and new adventures as she strives to help Mother all she can. And though this first year on their own also brings Caroline and her family great hardship, they survive with courage and love.
