What is the plot resolution of A Thousand Splendid Suns?

After Mariam's tragic and horrific death by public
execution in one of the infamous stadiums in Afghanistan that are used for such
executions, Laila and Tariq run away with both of Laila's children and live for a while
in Pakistan as refugees. However, in a novel that is dominated by such a fierce
passionate love of Afghanistan, as symbolised by the poem where the title is taken from,
they yearn to return to their homeland. The US invasion of Afghanistan gives them this
opportunity and they return to Kabul. The novel ends on a hopeful note as we are shown a
couple that genuinely loves and is committed to each other and their country, in spite
of all of the many sufferings, cruelties and the harshness of life in Afghanistan. This
gives us hope of a brighter future as such individuals work to try to restore something
of Afghanistan's fabulous past in the bitter, war-torn present.
