Egyptian psychiatrist Basma Abdel Aziz has long counseled survivors of torture and political repression, and she writes about the collective trauma inflicted by brutal autocratic regimes. Her latest novel, "The Queue," takes place after a popular revolution has toppled one dictator, only to have another faceless authority take his place. She says that even though present-day Egypt resembles the country under Hosni Mubarak, the Tahrir Square protests transformed the nation in a very important way — they helped embolden citizens who for decades were gripped by fear.
