In the late 1800s, a woman named Mary Fields broke every rule people thought they knew about the Wild West. She wasn't a cowboy, an outlaw, or a sheriff-she was something even more extraordinary. At sixty years old, she climbed onto a stagecoach, gripped the reins, and became the first Black woman mail carrier in the United States. Her story is one of grit, courage, and heart. She drove teams of horses through blizzards, across rushing rivers, and down trails where outlaws waited to strike. With a rifle by her side and determination in her soul, she delivered the mail when others couldn't. But her toughness was only half the story. She was also known for her generosity-sharing food with hungry children, helping neighbors in need, and standing up for fairness whenever she saw someone being treated wrongly. This book brings her remarkable life to young readers, showing how she went from enslavement in Tennessee to becoming a legend of Montana's frontier. Packed with true stories of her adventures, challenges, and triumphs, it offers kids a chance to meet one of history's most inspiring women. Her life proves that courage and kindness can change the world-and that even one person can make history.
