"Despite being described as a "crossover" it's not a traditional cross over in the sense that the story continues from one book to another, instead, each book will have their own self contained story about the Court's attack on Gotham, and the hero who fights against them. Titles involved with the cross over are Batman, Nightwing, Batman and Robin, Batgirl, Batman: The Dark Knight (featuring Tim Drake,) Birds of Prey, Catwoman, Batwing, Red Hood and the Outlaws, and All-Star Western. DC would later announce that Detective Comics would indeed tie into the event, originally being solicited otherwise."
Looks like I won't be Nightwinging any time soon
