The Red River of the North series by Lauraine Snelling takes up an entire shelf of one of my bookcases.
The Red River of the North is actually the name given to the first six books about Ingeborg Bjorklund and Kaaren Knutson, their husbands, and children, and their journey from Norway to Dakota Territory. The tales of the town of Blessing continue in the three books of the next series, Return to Red River, and in the four books of Daughters of Blessing. Then came grandchildren and Home to Blessing (three books) and Song of Blessing (four books). Lauraine Snelling also wrote a prequel, An Untamed Heart.
Christian Historical Fiction is the genre and the books (all twenty-one of them) are a delightful read.
