Khaled Hosseini was born in Kabul, Afghanistan, in the year 1965. A few years later, in 1976, they moved to Paris after his father obtained a job in France. They could not return to Afghanistan because of the Saur Revolution, in which the PDPA communist party seized power through a bloody coup in April 1978. Instead, a year after the Soviet invasion of Afghanistan, in 1980, they sought political asylum in the United States and made their residence in San Jose, California. Hosseini went forward to complete his education in the United States - he earned his MD from the University of California, San Diego, School of Medicine. He was practising medicine when he wrote the book 'The Kite Runner.
When a true friendship blooms, society or the class doesn't matter. Amir was best friends with their servant's son, Hassan. They grew up together, travelled through the lanes of a small town in Afghanistan hand in hand, and played every game together. In one such event, Amir and Hassan emerged victorious in a Kite race; Hassan went back to claim the kite and was sexually assaulted by a local gang. Amir couldn't protect his best friend and, in an attempt to escape the guilt, manages to frame Hassan and his father in a theft case at his house. Decades later, Amir learns that Hassan has passed away, leaving behind a child in an orphanage, when Amir reaches an Afghan terrorist who had already captured Afghanistan from the US, Hassan's little son. In an attempt to save Hassan's son, he delved into a fist fight with the terrorist and ultimately, when he would have lost his life in the battle, Hassan's son saved him with a slingshot - something passed down from his father. Both are safe, now return to the US to start a life as a family, and Amir runs to catch the kite as his best friend did during their childhood.
After her mother succumbed to suicide, Mariam was forced to marry a shoemaker in Kabul as she was her father's illegitimate daughter. The deal was made to bid a forever goodbye to Mariam so that she never returns to her distant family. Day after day, Mariam realised her mother's words were valid, that her father never actually cared for her and couldn't stand up to protect her, and the day she stepped out of the boundaries set by her mother was when she lost her mother too. Her paths cross with Laila, who was born much later, practically from another generation where under terrible conditions, she was forced to marry Mariam's husband, Rasheed. For years, Mariam had survived through the torcher and assault of her husband, but when Laila delivered a 'girlchild' and became the centre of the assault too, something snapped in her, and she came to her senses. Mariam fights to save Laila and her daughter's life and finally helps Laila reunite with her long-lost lover at the cost of her life.
A father in a distant land decides to narrate a fable to his children about a farmer who had to give up one among his five children to the giant; unfortunately, when the farmer and his wife chose their favourite child, the farmer was unable to overcome the grief and started on the journey to bring his son back. But, when he finds his son surrounded by the luxury of freedom, beaming with happiness as he plays with other children his age, completely ignorant about his family, he decides that it is for the best to leave him to be happy instead of struggling due to poverty with the family. But, the farmer's story was indirectly linked to the father narrating it to his children, Pari and Abdullah - about to be separated. As the story proceeds, Pari is adopted by a poet who lives in Paris, leaving behind Abdullah. But, howsoever might be the condition, the siblings were tied with the tender innocent love and the small habits they acquired in their childhood, like the collection of feathers. They meet decades after Pari receives a phone call and reunites with her niece, her brother Abdullah's daughter - also named Pari. As Abdullah had dementia, he could not recognise his sister Pari whom he had longed for many years. Eventually, he hands over the 'box of feathers' to Pari, and she is content to know that her brother never forgot her.
