A Thousand Splendid Suns is a look at the lives of Afghani women, especially contrasting the lives of two women, one older than the other, raised in completely different pre-Taliban contexts, who end up, because of the nation's particular tragedies, married to the same despotic man. The younger was viewed at first by the older as the rival wife, to be fought. A friendship, in reality, a kinship (mother-daughter; older sister-younger sister), was formed. Like Hosseini's earlier book, as a master storyteller, this account is riveting. It is not a pleasant read, but it is valuable.
I had a student who spent a long time in Kabul, working with an NGO. He recommended another book on Afghanistan, title The Book Seller of Kabul, by Asne Seierstad. Though written based on the experiences of a non-Afghani who spends significant time there, it also allows foreigners a view from the inside.
I recommend all three of these books. You might want to check them out.
