Today, the Justice League of America is legendary—the greatest superhero team ever established. But a decade ago, the League’s founders were just five individual crime-fighters: the Flash, Green Lantern, Aquaman, Black Canary and Martian Manhunter, protecting their own regions of the country, but never crossing paths. Then, a threat too large for just one hero brought them all together, setting the foundation for the most famous team-up of all time!  Acclaimed authors Mark Waid (KINGDOM COME), Brian Augustyn (BATMAN: GOTHAM BY GASLIGHT) and Barry Kitson (LEGION OF SUPER-HEROES) take the JLA back to its roots in this fan-favorite storyline. Reprinted here for the first time in hardcover, this special deluxe edition includes the full 12-issue miniseries, with an introduction by writer Mark Waid.
