The Girl in the Thistles by S.K. Sandvig
Emilie, the 19-year old daughter of a Sioux mother and a Scottish father, finds her home destroyed when her clan is caught up in the US-Dakota war of 1862. Her mother is sent to a prisoner-of-war camp, and Emilie sets out to find her father, who has been missing since the beginning of the war. With help from two new and unlikely friends, Eustis and Anders, she begins a treacherous and emotional journey to track him down. Will she find him? Will her mother be set free? And will Emilie be able to rebuild the home she’s lost?
