It has been over a decade since Marion Crook arrived in the Cariboo for her first job out of nursing school. The vast rural territory that once left her awestruck now feels like home, as she embraces life on the ranch with her husband, Carl, three young children, and numerous farm animals. But things are far from idyllic. Overseeing a small staff of irrepressible nurses serving a public health district the size of a small country brings new challenges every day. From runaway patients and needle-phobic hockey players to cultural misunderstandings and heartbreaking cases of abuse and neglect, Marion never knows what is coming next. The 1970s bring signs of social progress as women gain more autonomy and the region grows more culturally diverse. Yet, old prejudices persist, and Marion must fight for her patients, as well as for her adopted son. Recounted with warmth, compassion, and riveting detail, Always On Call is a fascinating portrait of the hectic life of a rural nurse and highlights the importance of the helping professions.
