Nobody can measure up to Nealy Coleman Diamond's standards as a trainer, not even her daughter Emmie, who now runs the family's Blue Diamond Farms. When Nealy she returns to the stables for a family reunion, she realizes that Emmie has let the farm slide and has picked a small, gutsy colt to send to the Derby--a nice horse, but clearly the wrong one. Suddenly Nealy is back in the game, ready to prove she's not too old to back a winner--even if means taking on another colt as her own personal project.

Now Emmie and Nealy engage in an unstoppable rivalry, one that may irreparably damage their relationship. Each is determined to win--no matter what the dangers, no matter what the cost.
