I recently read the Kite Runner book by Khalid Hosseini which revolves around two main characters Amir and Hassan and sins of Amir Agha. The whole story is well structured and every events are well written.
The place of story revolves around Afghanistan, Pakistan and America.
The sin of Amir Agha let him to separate from his best friend Hassan and at last his sin never let him sleep.
At last the one thing that is revealed that Hassan is actually his brother twist the story and murder of Hassan with his wife by Talibans make him low.
Overall story is really magnificent. One must read this amazing book.
