JLA: Act of God (2000-) #3

All of Earth's heroes losing their powers signals the start of a new era. From the ashes rises the Phoenix Group, a post-super-powered band that has trained under Batman to carry on the tradition of superheroes, but without the powers. Aquaman, Supergirl, Martian Manhunter and the Flash rededicate themselves to being humanity's greatest heroes. But will they rise to the occasion when confronted with their first great challenge, or fall by the wayside like Earth's other heroes?
