This book presents a deeply researched biography of Laura Ingalls Wilder, the author of the "Little House on the Prairie" series. It provides an in-depth look into Wilder's life and the historical context in which she lived, from the westward expansion to the Great Depression and beyond. The narrative explores the complex relationship between Wilder and her daughter, the hardships they faced, and the ways in which these experiences shaped Wilder's writing. It also delves into the myths and realities of American frontier life, challenging the often-romanticized view of pioneer life.

The book explores the concept of the frontier throughout American history, arguing that it has been a central myth that has shaped the nation's ideologies and policies, from its inception to the present day. The author traces this myth from the country's founding, through westward expansion, to the current political climate and the contentious issue of the border wall. The book suggests that the frontier has served as a symbol of freedom and opportunity, but also of conflict and exclusion, reflecting the country's struggle with its own identity and values.
