Millions of readers of Little House on the Prairie believe they know Laura Ingalls - the pioneer girl who survived blizzards and near-starvation on the Great Plains. Her books are beloved around the world. But the true story of her life has never been fully told. The Little House books were not only fictionalized but brilliantly edited, a profound act of myth-making and self-transformation. Now, drawing on unpublished manuscripts, letters, diaries, and land and financial records, Caroline Fraser masterfully fills in the gaps in Wilder's biography, setting the record straight regarding charges of ghostwriting that have swirled around the books and uncovering the grown-up story behind the most influential childhood epic of pioneer life. Set against nearly a century of epochal change, from the Homestead Act and the Indian Wars to the Dust Bowl and the Great Depression, Wilder's dramatic life provides a unique perspective on American history and its national mythology of self-reliance. Settling on the frontier amidst land-rush speculation, Wilder's family encountered Biblical tribulations of locusts and drought, fire and ruin. Deep in debt after a series of personal tragedies, including the loss of a child and her husband's stroke, Wilder uprooted herself again, crisscrossing the country and turning to menial work to support her family. In middle age, she began writing a farm advice column, prodded by her self-taught journalist daughter. And at the age of sixty she turned to children's books, recasting her hardscrabble childhood as a triumphal vision of homesteading - and achieving fame and fortune in the process, in one of the most astonishing rags-to-riches stories in American letters. Offering fresh insight and new discoveries about Wilder's life and times, Prairie Fires reveals the complex woman who defined the American pioneer character, and whose artful blend of fact and fiction grips us to this day.
