““People were differentiated by this substance, which was called nganon . Nganon was a concentrate which was defined in each person by nurture and circumstance. She believed that she and a certain few others were not of the same nganon as the rest of Earth's people. At first Deborah had thought that it was only she who was set apart from human kind, but others of the un-dead on D ward seemed to be tainted as she was. All of her life, herself and all her possessions had been imbued with her essence, the poisonous nganon . She had never lent her clothes or books or pencils, or let anyone touch any of her things, and she had often borrowed or stolen from other children at school or camp, delighting, until their stolen nganon wore off them, in the health and purity and grace of the possessions.””
