What is the theme in The Bookseller of Kabul by Asne Seierstad?

One of the most prevalent themes of the book is the unhappiness of the people, especially the women. The women have few rights in Afghan society, especially when it came to marriage. All marriages were negotiated between the families. Women cannot date or be seen in public with men without their families consent. They have to wear the burka which only leaves their eyes exposed. The women are totally under the domination of the men in their family.
