Mae thought of his hands. His hands had ruined her. All she wanted at that moment was his hands upon her again. His hand on her sacrum, pulling her close. Could her desires be so simple? And where in the hell had he gone? He had no right to disappear like this. She checked CircleSearch again; she’d looked for him a hundred times this way, with no success. But she had a right to know where he was. To at least know where he was, who he was. This was the unnecessary, and antiquated, burden of uncertainty. She could know, instantly, the temperature in Jakarta, but she couldn’t find one man on a campus? […] Mae cursed the not-knowing, and knew she needed someone who could be known. Who could be located.
