Batman faces his greatest enemy as Chip Zdarsky's run reaches its decisive and dramatic conclusion, presented in the second of two omnibus hardcovers. As Gotham descends into chaos, Batman faces challenges that strike at the core of his mission, his relationships, and his sense of self. With the Bat-Family divided and trust fractured, the battle for Gotham becomes as personal as it is physical. At the center of it all lies a terrifying realization: The greatest threat to Batman may be Batman himself. As his backup persona, Zur-En-Arrh, rises to the surface, the conflict becomes an internal war that pushes Bruce Wayne to his limits. In this omnibus collected edition, writer Chip Zdarsky is joined by superstar artists including Jorge Jiménez and Giuseppe Camuncoli for "The Gotham War," "The Joker Year One," "Mindbomb," and other thrilling story arcs.
