A Thousand Splendid Suns LRB #4

In part four of Khaled Hosseini's, "A Thousand Splendid Suns", the story ends by having the two continue on the journey of life. Laila and Tariq live in Pakistan for a few years, and then they journey to Herat. She feels like she needs closure, and so she goes to seek it. Then she decides that she wants to go back to Kabul. So they do. Then Laila works as a teacher at the orphanage, and Tariq works to fix it. That's how the story ends.
