Widow 1881 by Sara Dahmen

Proper Boston widow Jane Weber moves to the Dakota Territories under layers of lies to save her reputation. Stirring up controversy, Jane rooms with the last Blackfoot Sioux in town while navigating a mercurial friendship with the fiercely independent town grocer. In Flats Junction, though, everyone has an untold story. Battling her shortcomings, falsehoods, and swallowing her inherent curiosity, Jane must choose how she will truly reinvent herself, and where she belongs.
