Book excerpt: Two horses, twin brothers at birth, couldn't be more different. Big Brother, the larger, stronger horse has the physique of a champion. He is the sensation of the horse-racing world. But Little Brother - smaller, pigeon-toed, and hidden away - has the heart of a winner. The racehorse breeder and his family who nurture him with love believe he deserves his chance. But, can Little Brother beat his much-favored sibling when their paths cross at the most famous of all horse races, the Kentucky Derby? In this semi-autobiographical story, veteran jockey Alan Patterson takes you into the world of professional horse racing, where the will to win is a must, but the love for horses makes the difference.
