But no one knows for sure when it will reopen, due to the clashes between Afghan nationalist forces and the Islamist group that have ensued since troops from the United States began withdrawing in May. Now, Husna’s only ray of hope is the mobile library run by the Pen Path Civil Society, a nongovernmental organization whose motorcycle-riding volunteers travel across areas ravaged by fighting to distribute books and stationery to children.”
