"Edge City: Life on the New Frontier" is a book by author Joel Garreau that explores the rise of suburban areas that have transformed into vibrant urban centers. These "edge cities" are characterized by their mix of residential, commercial, and recreational spaces, often located near major highways. Garreau examines how these developments reflect changing lifestyles and economic patterns in America. The book highlights the social and cultural implications of edge cities, including shifts in work, transportation, and community dynamics. Garreau argues that these areas represent a new frontier in urban living, challenging traditional notions of city and suburb.
