The Dark Knight was young, inexperienced and untested when he began his one-man war to save the soul of Gotham City. The vigilante known as Batman was new to the city's dark streets, and his errors were costly. Though his mind, body and arsenal of crime-fighting gear were all honed to near-perfection, his methods were yet unproven.

But Batman's rookie lessons were just the prelude to far more desperate tales.

Despite becoming an outlaw himself after quelling the Arkham Asylum riots, the World's Greatest Detective takes it on his shoulders to unravel why the new mayor, Quincy Sharp, wants to create Arkham City--a section of Gotham where heinous criminals and the insane can roam freely. Now not only is the Dark Knight up against City Hall, but also the amassing armies of his numerous enemies--the Penguin, Two-Face and even The Joker himself.

On top of the machinations of Batman's full rogues gallery, a new vigilante emerges--the Arkham Knight. It's a life-or-death battle unlike any other for the Caped Crusader's allies and enemies, with no end in sight
