Based on actual oral histories of survivors, this gripping novel follows the stories of Raina and Gerda Olsen, two sisters, both schoolteachers--one becomes a hero of the storm and the other finds herself ostracized in the aftermath. At its heart, this is a story of courage, of children forced to grow up too soon, tied to the land because of their parents' choices. It is a story of love taking root in the hard prairie ground, and of families being torn asunder by a ferocious storm that is little remembered today--because so many of its victims were immigrants to this country.
