Publisher's Synopsis
One of the most monumental crossovers in DC history is now collected in a brand-new hardcover with ZERO HOUR! All of reality comes under attack when a mysterious force of entropy begins slowly erasing time itself-making its way from both the past and future toward the present! As history itself unravels around them, the heroes of the world-including Superman, Batman, Wonder Woman, The Flash, The Justice Society and the Titans-scramble to fix the broken timestream. But even if they stop the true source of the chaos, the world they save will never be the same! Written and illustrated by industry legend Dan Jurgens, along with Jerry Ordway and others, this graphic novel now tells the entire saga in it's entirety. ZERO HOUR collects ZERO HOUR: CRISIS IN TIME #4-0.
