Walls reimagines the life of her grandmother, Lily Casey, who by age six was helping her father break horses. At 15, she left home to teach in a frontier town--riding 500 miles on her pony to get to her post. She learned to drive a car, fly a plane, and with her husband, managed a vast ranch in Arizona, surviving tornadoes, droughts, floods, and the Great Depression.

Jeannette Walls graduated from Barnard College and was a journalist in New York. Her memoir, The Glass Castle, has been a New York Times bestseller for more than eight years. She is also the author of the instant New York Times bestsellers The Silver Star and Half Broke Horses, which was named one of the ten best books of 2009 by the editors of The New York Times Book Review. Walls lives in rural Virginia with her husband, the writer John Taylor.
