Or was that what she wanted?

The lights of the town dropped behind. Half a mile out, he turned off sharply onto the road that wound up the hill. It was bumpier than he remembered from the last time—was it as much as ten years ago? And the trees were thicker, brushing the windshield.

She rested her head on his shoulder. He switched off the headlights, and the moon cast soft shadows.
