Astrid and Joshua discover God's plans for them through difficult circumstances in the conclusion to this prairie romance series set in South Dakota.

Ma and the girls follow Pa west by train where they make their home at a rough railroad camp and plan for their own homestead.

On the empty winter prairie, gray clouds to the northwest meant only one thing: a blizzard was seconds away. The first blizzard came in October. It snowed almost without stopping until April. The temperature dropped to forty below. Snow reached the roof-tops. And no trains could get through with food and coal. The townspeople began to starve. The Ingalls family barely lived through that winter. And Almanzo Wilder knew he would have to risk his life...

With a secretive widow, a love-struck cowboy, and a suspicious rancher standing in her way, will Cassie ever fulfill her father's last wish?

Hoping to escape the attention brought on by the accident that flattened Stanley, the Lambchop family drives to South Dakota, where they become involved in a wild west adventure at Mount Rushmore.
