Amir is the son of a wealthy Kabul merchant, a member of the ruling caste of Pashtuns. Hassan, his servant and constant companion, is a Hazara, a despised and impoverished caste. Their uncommon bond is torn by Amir’s choice to abandon his friend amidst the increasing ethnic, religious, and political tensions of the dying years of the Afghan monarchy, wrenching them far apart. But so strong is the bond between the two boys that Amir journeys back to a distant world, to try to right past wrongs against the only true friend he ever had.
