This volume sees the reunited JSA face the foe that decimated their ranks years prior: Extant! Also, the stunning, much ancitipated return of Hawkman! Mixing classic heroes such as Green Lantern, the Flash and Wildcat with a younger generation of crime-fighters like Starman, Black Canary, Hawkgirl, Atom Smasher and the Star-Spangled Kid, Johns revitalized the series and began a career that would see him write such incredible graphic novels as JUSTICE LEAGUE VOL. 1: ORIGIN, BLACKEST NIGHT, BATMAN: EARTH ONE VOL. 1, FLASHPOINT, INFINITE CRISIS, DC UNIVERSE: REBIRTH and many more! With contributions from David S. Goyer (screenwriter for THE DARK KNIGHT TRILOGY), James Robinson (STARMAN) and more, this series set into motion one of the great runs in comics history! Collects JSA #6-20, SECRET ORIGINS OF SUPER VILLAINS #1.
