When Susannah goes to Dakota territory as a mail-order bride she finds something she never dreamed she would - true love.
With no prospects for marriage and her parents recently deceased, Susannah Underhill agrees to go west to the Dakota territory to marry her minister's homesteading brother, Jesse. But Susannah is painfully shy, doesn't see herself as worthy of love from either a husband or from God, and lives in constant fear that Jesse is going to ship her back to Detroit.
In spite of her petite size and the fact that Susannah doesn't look like she could survive on the prairie, Jesse quickly discovers that his new wife is a greater blessing than he even hoped for. The years she spent as her father's veterinary assistant allow her to save Jesse's ox and twin calves and to help neighbouring farmers with their animals.
But Susannah's feelings of unworthiness are deeply rooted, and she can't believe that Jesse's praise...or the tenderness and love he shows...could possibly last. The thawing of her heart seems almost as distant as Spring in the midst of the winter blanketing the Dakota prairie.
