Book excerpt: Born into an African American sharecropping family in 1880s Kentucky, Jimmy Winkfield grew up loving horses. The large, powerful animals inspired little Jimmy to think big. Looking beyond his family's farm, he longed for a life riding on action-packed racetracks around the world. Like his hero, the great Isaac Murphy, Jimmy "Wink" Winkfield would stop at nothing to make it as a jockey. Though his path to success was wrought with obstacles both on the track and off, Wink faced each challenge with passion and a steadfast spirit. Along the way he carved out a lasting legacy as one of history's finest horsemen and the last African American ever to win the Kentucky Derby. The Last Black King of the Kentucky Derby brings to life a vivacious hero from a little-known chapter of American sports history. Readers are transported trackside to witness the heart-pounding story of a vibrant young man chasing down his dream.
