Reader Friday: Description

She sat up slowly, looked in turn at each of us, and her dark eyes were like twin entrances to two deep caves. Nothing lived in those caves. Maybe something had, once upon a time. There were piles of picked bones back in there, some scribbling on the walls, and some gray ash where the fires had been. (Darker Than Amber by John D. MacDonald)
