Drawn partly from a true story, a searing, totally immersive novel about a devastating Native American revolt, and a woman caught in the middle of the conflict.

In the summer of 1855, Sarah Brinton abandons her husband and child to make the long and difficult journey to Minnesota, where she will meet a childhood friend. Arriving at a small frontier post on the edge of the prairie, she discovers that her friend has died of cholera. Without work or money or friends, she quickly finds a husband who will become the resident physician at an Indian agency on the Yellow Medicine River. As one of the earliest settlers in the area, Sarah anticipates unease and hardship, but instead finds acceptance and kinship with the Sioux women who live on the nearby reservation. She learns to speak their language, nourishing a companionship with them which far exceeds that which she shares with her strange and distant husband.
