Pa's homestead thrives, Laura gets her first job in town, blackbirds eat the corn and oats crops, Mary goes to college, and Laura gets into trouble at school, but becomes a certified school teacher.

During their first four years of marriage, Laura and Almanzo Wilder have a child and fight a losing battle in their attempts to succeed at farming on the South Dakota prairie.

Laura has her first experiences as a teacher, and is courted by Almanzo Wilder. Fifteen-year-old Laura learns that living away from home and teaching school can be a bit frightening when most of the students are taller than she is, but every week Almanzo Wilder arrives to take her to her family for the weekend.
