Laila is born in Kabul on the night of the coup of April 1978. During her first fourteen years, she spends most of her time with her best friend, Tariq. Soon after the Mujahideen start bombing Kabul, Tariq and his parents flee to Pakistan, Laila's parents are killed, and Laila reluctantly consents to become Rasheed's second wife. She and Mariam eventually form a strong bond.

But he marries her off as soon as she gets in his way. Rasheed, Mariam and Laila's husband, forces them to wear burkas and abuses them whenever they displease him. Tariq, Laila's best friend and childhood sweetheart, returns to Afghanistan to see Laila. The two eventually marry.
