I have just finished Iranian author and filmaker Siba Shakib's book Afghanistan, Where God Only Comes To Weep.
It is unrelenting in its grimness, and reminded me of Steinbeck's The Grapes of Wrath. One of the descriptions of mutilated Russian soldiers made me feel ill for days.
The book tells the story of Shirin-Gol (which means sweet flower)and her life in refugee camps, under the Taliban and civil war in general. Depressing reading, and an up close look at the reality of the lives of millions.
