During the tirade, Nan slipped down into the ditch, where she moved aimlessly about in the long grass like someone lost. When she returned she had in her palm a small, round stone as smooth as glass. “It's a sick-stone,” she explained when his grandfather had gotten back in the car. She placed it in Reef’s hand and closed his fingers over it. “When you feel like you’re gonna throw up, just squeeze it hard. It’ll take the sick feelin’ away.” It worked. Each time the waves of nausea rolled up over him, he gripped that stone like a lifeline, trying not to watch his grandfather’s thick fists pound the horn at whoever was stupid enough to cut him off. And each time he squeezed that rock, he felt stronger, like he was somehow in charge.
