Seventeen-year-old Adam and his parents are driving home to Rhode Island from a peace rally in Seattle when the accident happens. In a single, horrible moment, his parents are gone. And Adam is alone. In a speechless state of shock, Adam begins walking across the country, toward home. But he can't think in a straight line: The past and present merge in his thoughts, and the future's a blank. As flashes of memory come to him -- some wonderful, some violent -- he begins to wonder if he has truly lost everything.
