She ll never be a racehorse, murmurs the crowd as Black Minx is led into the sales ring. But Alec Ramsay thinks differently and buys the Black s first filly to train her for the Kentucky Derby. But Black Minx, like her sire, has a mind of her own. This fast-paced racing story follows a great horse s journey through training and preliminary races to the opening gate at America s most famous racetrack: Churchill Downs.
