Batman - Greg Rucka

Gotham City: a dark, twisted reflection of urban America. Overcrowded, overbuilt, and overshadowed by a continuous air of menace. This gothic nightmare is a breeding ground for the depraved, the indifferent, and the criminally insane. It's also the object of one man's obsession. Forever scarred as a child from witnessing the brutal murder of his parents, Bruce Wayne has dedicated his life to protecting this city from its many predators. He is the masked vigilante known as the BATMAN.
But now, levelled by a massive earthquake that has left thousands dead and millions more wounded, Gotham City has been cut off from the outside world and transformed into a lawless battleground where the survivors are turning against each other. And in these darkest of hours, BATMAN is missing.
