A much-needed alternative history of American comic book superheroines—from Wonder Woman to Supergirl and beyond—where they fit in popular culture and why, and what these crime-fighting females say about the role of women in American society from their creation to now, and into the future. The Supergirls is an entertaining and informative look at these modern-day icons, exploring how superheroines fare in American comics, and what it means for the culture when they do everything the superhero does, but in thongs and high heels.
