Hope Within (Heirs of Montana Book #4) 

1886 Montana stands on the brink of statehood, and Dianne Selby finds her world turned upside down. Cole takes her and the children to Kansas to care for his dying father, but after the funeral, Cole’s mother insists he stay and take over his inheritance. Unable to deal with her mother-in-law’s cruel treatment, Dianne takes the children back to Montana alone. There, blizzards devastate the area, trapping a now pregnant Dianne at the ranch. Through the twists and turns of life and nature, Dianne comes to realize that the hope within–Jesus Christ–is the only hope that lasts. Book 4 of the bestselling Heirs of Montana.
