Becky McCabe hails from a long line of female show-jumpers. When her steely mother, Maggie, who had been training for the Olympics, falls and injures her pelvis, Becky agrees to enter the competitions that will determine the U.S. Olympics team in her stead. This proves too much for Maggie, who quickly rallies and seeks to compete against her own daughter. Bestselling thriller author James Patterson teams up with prominent sport writer Mike Lupica to conjure a rarefied world of ribbons and champagne, yet the novel's greatest achievement is the incorrigible mother-daughter pair at its center.
