Leilani lifts a rough stone from the tray, rubs it once on her apron and holds it to the lamp. It glows amber from the inside. She watches your face. "Look closer. There. That glow was in there all along. I never sell this kind. Ask me why, and I will show you the one I keep." The tide is low and the stones are wet. Come to the bench, hold one to the light and tell me what you see. Everyone sees something different.
