Considered one of Sweden's greatest 20th-century writers, Vilhelm Moberg created Karl Oskar and Kristina Nilsson to portray the joys and tragedies of daily life for early Swedish pioneers in America. His consistently faithful depiction of these humble people's lives is a major strength of the Emigrant Novels.

Moberg's extensive research in the papers of Swedish emigrants in archival collections, including the Minnesota Historical Society, enabled him to incorporate many details of pioneer life. First published between 1949 and 1959 in Swedish, these four books were considered a single work by Moberg, who intended that they be read as documentary novels. These editions contain introductions written by Roger McKnight, Gustavus Adolphus College, and restore Moberg's bibliography not included in earlier English editions.

Book 4 portrays the Nilsson family during the turmoil of living through the era of the Civil War and Dakota Conflict and their prospering in the midst of Minnesota's growing Swedish community of the 1860s-90s.

"It's important to have Moberg's Emigrant Novels available for another generation of readers."―Bruce Karstadt, American Swedish Institute
