La hermana de la delantera (Striker's Sister)

Lily Davis's big sister and star soccer player, Jana, has left home for basic training, and now Lily's parents and coach want her to change positions, from goalie to striker, wear Jana's jersey, and fill her sister's shoes--at first she goes along with the switch, until a letter from Jana gives her the courage to tell them all that she is her own person, and that person is a goalie.
