A thousand Splendid Suns was written by Khaled Hosseini, American writer of Afghan origin who became world famous in 2007 with the adaptation of his novel The Kite Runner to a film of the same name.
Whereas The Kite Runner dealt mostly with the world of men and the friendship between them, A Thousand Splendid Suns deals with women before and after the Taliban invasion.
It tells the story of two women from two different backgrounds (within Afghan culture) and how their lives become one. Mariam is the daughter of a rich man, but she’s a harami, an illegitimate child, and when her mother dies her father’s family marries her off to Rasheed, a shoe maker from Kabul. Laila is the daughter of an intellectual and is in love with her neighbour and best friend who leaves Kabul with his family just before both her parents get killed. Mariam’s and Laila’s stories become one when Laila sees that she has no choice but marry Rasheed.
It tells the story of the two women and it tells the story of Afghanistan. I think it’s an attempt at explaining how things reached the point they have in Afghanistan. To show that it was a normal country with a normal society before the Taliban imposed the Sharia.
