We want to send you a copy of Glen Weldon’s The Caped Crusade: Batman and the Rise of Nerd Culture, available March 22 from Simon & Schuster! Since his creation, Batman has been many things: a two-fisted detective; a planet-hopping gadabout; a campy Pop-art sensation; a pointy-eared master spy; and a grim and gritty ninja of the urban night. For more than three quarters of a century, he has cycled from a figure of darkness to one of lightness and back again; he’s a bat-shaped Rorschach inkblot who takes on the various meanings our changing culture projects onto him.
