The Namesake by Jhumpa Lahiri

Meet the Ganguli family, new arrivals from Calcutta, trying their best to become Americans even as they pine of home. The name they bestow on their firstborn, Gogol, betrays all the conflicts of honoring tradition in a new world - conflicts that will haunt Gogol on his own winding path through divided loyalties, comic detours, and wrenching love affairs.
