Here's why:
* Based on real events: The book draws heavily from Laura's own childhood experiences in the 1880s, specifically the harsh winter of 1880-1881 in De Smet, South Dakota.
* Historical setting: The story is set in a specific time period (late 1800s) and location (the American frontier), with descriptions of the daily life, customs, and challenges of that era.
* Realistic portrayal: While fictionalized, the book aims to depict the hardships of life on the frontier, including the struggles with the blizzard, food shortages, and isolation.
* Focus on personal experiences: Though set against a historical backdrop, the story primarily focuses on the Ingalls family and their personal journey through the harsh winter, making it a coming-of-age tale.
Although the book is categorized as historical fiction, it also has elements of adventure (due to the challenges and resourcefulness of the characters) and family drama (due to the strong focus on family relationships and their dynamics).
