Book excerpt: In this haunting, bracing new collection, Dan Chaon shares stories of men, women, and children who live far outside the American Dream, while wondering which decision, which path, or which accident brought them to this place. Chaon mines the psychological landscape of his characters to dazzling effect. Each story radiates with sharp humor, mystery, wonder, and startling compassion. Among the Missing lingers in the mind through its subtle grace and power of language.
