Girl Waits with Gun (Kopp Sisters #1) by Amy Stewart; 2016. Hardcover.

Constance Kopp doesn’t quite fit the mold. She towers over most men, has no interest in marriage or domestic affairs, and has been isolated from the world since a family secret sent her and her sisters into hiding fifteen years ago. One day a belligerent and powerful silk factory owner runs down their buggy, and a dispute over damages turns into a war of bricks, bullets, and threats as he unleashes his gang on their family farm. When the sheriff enlists her help in convicting the men, Constance is forced to confront her past and defend her family — and she does it in a way that few women of 1914 would have dared.
