Gotham City has always been a place of nightmares. But as Batgirl is about to learn the hard way, lately its dreams have been darker and more delirious than ever. A slayer who targets vampires and vigilantes alike. A terrifying urban legend turned all too real. A mercenary called Ragdoll who's made Gotham his latest plaything. The mega-rich killer of heroes named Knightfall who's all but got the city bought and paid for. Even the nightmare realm of Gothtopia, a place where everything is perfect-- for the price of your sanity. Now it's up to Batgirl and her allies in the Birds of Prey-- including a mysterious visitor known only as the Huntress-- to take this mad city back from the forces that threaten it.
