By Marv Wolfman. A mysterious force is moving through all levels of reality, destroying everything in its wake. Countless dimensions are being annihilated with each passing second. The world's greatest heroes - Superman, Batman, Wonder Woman, the Flash, and thousands of others - are confronted with their greatest challenge: stopping this interdimensional threat before it destroys all life in existence! In the wake of the 20th Anniversary of the Crisis on Infinite Earths comic book maxi-series (upon which this novel was based), original author Marv Wolfman revisits, expands, and reboots the events that changed the DC Universe (along with many of its characters) forever. SC, 5x8.25, 320pgs.
