Sách nói: Lisbeth Longfrock or Sidsel Sidsærkin

Lisbeth Longfrock - (Sidsel Sidsærkin in its original Norwegian) was seen by the author as a book written for adults, telling the story of a young girl growing up in a farming district in a steep-sided Norwegian Valley. It was first written when the author's daughter was 8 years old, the age of Lisbeth when the book begins, so she would know about his childhood spent in similar surroundings, living on a farm and spending summer in charge of the cows and goats on the mountain pastures.
