One Amazing Thing by Chitra Banerjee Divakaruni

Late afternoon in a passport and visa office in an unnamed American city. Most customers and even most office workers have come and gone, but nine people remain. A punky teenager with an unexpected gift. An upper-class Caucasian couple whose relationship is disintegrating. A young Muslim-American man struggling with the fallout of 9/11. A graduate student haunted by a question about love. An African-American ex-soldier searching for redemption. A Chinese grandmother with a secret past. And two visa office workers on the verge of an adulterous affair.
