In this sequel to Maggie Lou, Firefox, the irrepressible Maggie Lou acquires a new cousin, and a horse - both of whom have minds of their own. When Uncle Bobby gets married, Maggie Lou suddenly finds herself with a new cousin, Rosie. Rosie is the same age as Maggie. She also has a fabulous head of curls, although hers are red. And Rosie knows everything about horses and riding - something Maggie Lou has longed to do. A rivalry sparks between the girls from the start at Uncle Bobby and Aunt Bonnie's wedding, which features an all-you-can-eat dessert table, as well as lots of energetic dancing. On Rosie's horse farm, Maggie experiences her share of humiliations as she learns how to ride on a pony so short that her feet can touch the ground. Eventually the cousins become allies and wreak some hair-raising mischief, including a secret midnight horseback ride. And in the end they are joined by friends and family to train, hilariously, for the famous Otipîm'sowak Race - a Métis voyageur relay - carrying on a family tradition. Throughout it all, Maggie remains stubborn and enthusiastic, as she navigates the new challenges of defeat, rivalry and family change.
