Sister Amy Smithfield is carrying on her family's military tradition in the only way she can, as an Australian Army nurse. Dedicated to her calling, she has sworn off interest in men for the duration of the Great War in Europe. When she literally runs into Mark Tremayne, an English captain in the Australian army, her real struggle begins. Mark has his own reasons for keeping any relationship with the opposite sex in the casual mode, and he fights to deny his attraction to the petite blonde nurse who stirs his senses beyond the ordinary. Their battle against love continues from Australia to the Mediterranean to France. When Amy is captured by German soldiers, Mark realizes how much she means to him — but can he overcome pride and find Amy after his jealous anger pushes her away?
