Watchmen is a graphic novel—a book-length comic book with ambitions above its station—starring a ragbag of bizarre, damaged, retired superheroes: the paunchy, melancholic Nite Owl; the raving doomsayer Rorschach; the blue, glowing, near-omnipotent, no-longer-human Doctor Manhattan. Though their heyday is past, these former crime-fighters are drawn back into action by the murder of a former teammate, The Comedian, which turns out to be the leading edge of a much wider, more disturbing conspiracy. Told with ruthless psychological realism, in fugal, overlapping plotlines and gorgeous, cinematic panels rich with repeating motifs, Watchmen is a heart-pounding, heartbreaking read and a watershed in the evolution of a young medium.—L.G.
