For nearly 100 years, the “Little House” books (and the subsequent television series) have been cherished by kids and adults around the world. Millions of children have aspired to be like Laura Ingalls, a pioneer girl who courageously helped her family start new farms across the Midwest - planting, harvesting, hunting, and fighting blizzards.

The story of Ingalls’ family was based on the real-life adventures of Laura Ingalls Wilder, but Wilder’s real childhood was much harsher. As a child, Wilder endured “an almost brutal lifestyle,” according to Caroline Fraser, a Pulitzer-Prize winning writer, and author of the book “Prairie Fires: The American Dreams of Laura Ingalls Wilder.”

On this week’s show, Fraser talks to us about how Wilder reinvented American history, recast her own life, and what the books - and controversy over them - has to teach us.
