Justice League by Scott Snyder and James Tynion IV Omnibus Vol. 2

As the Justice League races to prevent the rise of Perpetua, the Legion of Doom enacts its grand plan to reshape reality itself. But as the ultimate battle between Justice and Doom erupts, a new darkness rises—the Batman Who Laughs. Twisting the very nature of heroism and villainy, he threatens to plunge existence into chaos. From the minds of Scott Snyder and James Tynion IV, this omnibus delivers universe-shattering stakes, mind-bending storytelling, and an all-out war for the soul of the DC Universe.
