According to Wikipedia: "Sigrid Undset (20 May 1882 – 10 June 1949) was a Norwegian novelist who was awarded the Nobel Prize in Literature in 1928. Undset was born in Kalundborg, Denmark, but her family moved to Norway when she was two years old. In 1924, she converted to Catholicism and became a lay Dominican. She fled Norway for the United States in 1940 because of her opposition to Nazi Germany and the German occupation, but returned after World War II ended in 1945. Her best-known work is Kristin Lavransdatter, a modernist trilogy about life in Scandinavia in the Middle Ages. The book was set in medieval Norway and was published from 1920 to 1922 in three volumes. Kristin Lavransdatter portrays the life of woman from birth until death. Undset was awarded the Nobel Prize in Literature for this trilogy as well as her two-volume work about Olav Audunssøn known as The Master of Hestviken tetralogy, published in 1925 and 1927."
