The Reapers Song (Red River of the North #4)
Lauraine Snelling

But for Ingeborg and Haakan, realizing their dreams will not come without a struggle. After their own fields are harvested, Haakan and the neighboring men take the steam engine and the separator on the road, threshing for other homesteaders in return for a portion of their grain. With Haakan away and the fields standing idle, Ingeborg frets over work yet to be done. Fearing an early change of seasons, she takes matters into her own hands.
Has the land become more important to Ingeborg than her own family?
