context: The story follows its title heroine, from childhood to confirmation. After her mother's death, Lisbeth (given the nickname Longskirt, or SidsÄÅrk in the original Norwegian, because of her much too-long skirt, a Christmas present given her by her brother) as she moves from her original home at New Ridge farm (called "Peerout Castle" for its fine view of the valley), to Hoel farm, one of the central farms of the area. Her brother, Jacob, also goes to Nordrum farm to become a herdsman there. At Hoel, Lisbeth is cared for by Kjersti Hoel, the farm's owner, who has made a promise to Lisbeth's mother before she died. Lisbeth works with livestock both at the farm, and at the seter (sÄÅter in the book's transliteration), a mountain pasture used during the summertime. At the seter, Lisbeth meets two other herdsmen from neighboring farms, and spends the summer with them, getting to know them as she grows up. The content of the book concerns the difficult conditions of the work of the country children who had to eke out a poor existence far away from their parents. In spite of this account of their hard lot an optimistic kind of portrayal is predominant.
