It's easy to see why Susanna Moore, who has written both fiction and nonfiction, was drawn to novelize the true story of Sarah Wakefield, a white woman who arrived in the Minnesota Territory in the mid-1850s and famously spent six weeks as a captive of Indians during the 1862 Dakota Conflict.
After the war, Wakefield was denounced for a book she wrote ("Six Weeks in the Sioux Tepees") that sympathized with her captors, including a warrior named Chaska, who saved the lives of her and her children and briefly counted Sarah as his wife.
The story has it all: the bloody hell of war, racism, sexism, true grit, culture clash, revenge, corruption, injustice. Even some romance. Is that Netflix calling?

Moore's undertaking, as a white woman writing about Native Americans, is fraught, to say the least.
While she succeeds in creating a vivid tale of frontier adventure and peril, her book is best seen as a portal to more reading (including the Wakefield book, still widely available) aimed at a fuller understanding of a watershed in Minnesota history.
In "The Lost Wife" Moore changes some but not all the names of historical figures. She has "added facts that I've discovered along the way, alongside much from my imagination."
Moore's Sarah, 25, flees an abusive husband in Providence, R.I., and travels alone to Shakopee, Minn.
A fearful and exhilarated Sarah describes her newfound freedom: "I don't know what to do with so much feeling. My life will now be one of improvisation. I hadn't known how easily a new life may be made." The frontier, for her, is both geographical and emotional.
