JLA, book 14 : Trial by Fire
Joe Kelly et Doug Mahnke2004

The Justice League of America comprises the greatest heroes the world has ever seen: Batman, Superman, the Flash, Martian Manhunter, Wonder Woman, Aquaman and the Green Lantern. Now the JLA's epic adventures continue! The President is in a coma, world leaders that usually can't agree a single thing in common are suddenly agreeing and die-hard criminals are seeing the error of their ways...there's definitely something strange going on. The Martian Manhunter attempts to probe every mind on the planet to find the mysterious entity responsible and gets a huge backlash in return. It's time to call in the JLA.
