Zach Watkins: Bloody Ground: A Mountain Man Adventure (A Zach Watkins: Early Frontier Mountain Man Western Adventure #3)
Peter Alan Turner

Soon the valley is in flames as Captain Franks and his men try to force the settlers off their land. When the homesteaders realize they’ll get no help from the governor, they elect Zach, Constable and charge Zach with driving Captain Franks out of the valley.
To complicate things, Waity announces she is pregnant. Zach promises he’ll be there for the birth of his child. However, when Zach is captured by the Hurons and sold as a slave to another tribe, Zach fears he’ll never see his wife and baby again. Now he must escape and travel back to Rollin’s Trading Post, stop Captain Franks’ harassment of the settlers, and still be there for the birth of his child.
