Crips and Bloods: A Guide to an American Subculture traces the evolution of the two gangs, covering their origins in South Central Los Angeles to the organizations' current presence throughout the United States. The author analyzes the ways in which the gang subculture is created, promoted, and perpetuated; shows how the groups currently recruit their members; and explores the ways Crip and Blood culture has expanded beyond the gangs into the larger mainstream society.
