Digging To America by Anne Tyler

Two families who would have never come together, meet by chance at an airport.  Each couple is waiting for the Korean child they have adopted.  The Donaldsons decide to invite the Yazdans to an arrival party, an event that is repeated every year as the two families become more deeply intertwined.  This was a great book that showed America in two different lights as the families decide how to raise their children.  It was funny and tender.  Just an all around good book.
