The book is comprised of a series of letters written by a young widow from Denver to her friend and former employer about the experience of homesteading in rural Wyoming in the early 20th century. She describes the people who inhabited this harsh landscape with empathy and humor, including migrants from the US and abroad, orphans, newlyweds and hermits. These people were settling the frontier at a time when our cities were experiencing rapid industrialization, creating an opportunity for a conscious juxtaposition of the quality of life in the beautiful but rugged wilderness, against the life that she had lived as a single mother trying to provide a good quality of life for her daughter in the city.
