Hazel Thornton has one great ambition: to help the sick and wounded as a nurse. But that dream can never become a reality. After a devastating childhood trauma, she has spent her life battling fits of panic that make it impossible to finish her studies. Everything changes, however, when a trip to Spain takes a perilous turn that derails her plans to visit her father for Christmas and immediately plunges her into the dangers of a brutal war. With single-minded focus, she springs into action to help her fellow travelers. To ensure their continued care, she begins work at a Spanish hospital alongside Dr. Jim Jackson, a man whose only emotion seems to be wariness of his new assistant. Armed with gifts of support from each of her dearest friends, a group that dubs themselves the Blue Orchid Society, Hazel embarks on a journey of hope and healing to battle the demons of her past with the help of the doctor who has captured her heart.
