Another step brought him to her side. For a moment he didn't turn his head. He stared forward, the rushing air cool against his eyes, his neck growing stiff with the effort of remaining still. Then he looked at her. Her eyes were a warm brown with flecks of green. They were full on him, as if she too had been staring. They were neither appraising nor aloof—but they weren't empty.
