It s the fourth volume of JSA by Geoff Johns, continuing the superstar writer s run on DC s original team of superheroes! In the Ultra-Humanite s latest world-conquering scheme, heroes from around the world including members of the JSA are vanishing, and those that remain must forge an unusual alliance with the Icicle to save the day. And with the JSA divided, handling multiple matters in different eras, several heroes find themselves in ancient Egypt, fighting the immortal villain Vandal Savage and an earlier incarnation of the powerful Black Adam. However, Power Girl and Dr. Mid-Nite also have their hands full with separate cases.
