The Namesake by Jhumpa Lahiri. From Amazon: In The Namesake, Lahiri enriches the themes that made her collection [Interpreter of Maladies] an international bestseller: the immigrant experience, the clash of cultures, the conflicts of assimilation, and, most poignantly, the tangled ties between generations. Here again Lahiri displays her deft touch for the perfect detail -- the fleeting moment, the turn of phrase -- that opens whole worlds of emotion."
