Nafisi was one of the fortunate ones, able to escape to the United States, where she continues to write and teach.
Khan and his family were, likewise, among the survivors of Afghanistan's political turmoil.
One of the few things to unite the three successive governments in Kabul - the communists, the Mujahedeen and the Taliban - was a hatred of free expression. As a leading bookseller, Khan fell foul of each in turn, seeing his stock destroyed and serving two terms in prison.
Nevertheless, he remained unharmed, as did 10,000 of his books, which he had hidden in attics throughout the city. With the fall of the Taliban, he was well-placed to expand his business, both as a bookseller and a publisher.
He invited Seierstad, whom he had befriended in his shop, to stay with his extended family and write about their lives.
Whereas Nafisi focuses on state tyranny, Seierstad exposes its domestic equivalent. Khan describes himself as a 'liberal man, not a fundamentalist'. Yet, to Western eyes, he appears as authoritarian as the Ayatollah.
He dominates his sons, refusing to allow the 12-year-old Aimal to attend school, insisting that he work 12 hours a day, seven days a week, selling confectionary in a hotel foyer in order to gain business skills.
Aimal's position is, however, infinitely preferable to that of the women in the family, who are treated as slaves by even their youngest male relatives.
This can be seen in its mildest form when Sultan's oldest son, Mansur, beats his aunt with impunity, and at its most savage when a relative is smothered to death by her three brothers for committing adultery.
Individually, these books paint a colourful portrait of people struggling to survive in the most brutal circumstances.
Together, they bear witness to the power of literature to withstand even the most repressive regime.
