Although the setting is startlingly different, and the care provided is through highly unorthodox means, the healer in this science fiction story experiences in remarkably similar ways the everyday wear and tear of modern medical practice. Snake, a young female itinerant healer, has been asked to save the life of a young boy. Her attempts to do so, and her interactions with the boy, his family and community, and the tools of her trade (the snakes-mist, sand and grass) are detailed in the story. "Professional development" issues that this strong and complex character has to deal with include truth-telling, interfering and ignorant family members, self-sacrifice, and possible reprobation by her peers and teachers.
The initial chapter in this novel, Of Mist, and Grass, and Sand (annotated separately), sets the stage for the quest of the young healer/heroine, "Snake," to find a replacement for the snake she had carelessly allowed to come to harm, in the course of caring for a seriously ill child. The remainder of this coming-of-age novel chronicles Snake's journey during her "proving year" (aka/residency training).
Over the course of this year, Snake continues to minister to the sick and encounters, among others, a patient who demands assistance in suicide, a patient who refuses treatment for a gangrenous leg, and a young girl who has been sexually abused (whom Snake eventually adopts and begins to apprentice). There are, as well, myriad lessons in humility, rigidity of thought, and ethnocentrism.
