The old saying "fight fire with fire" takes on new meaning as DC's Azrael meets Event Comics' Ash. The two heroes join forces to save New York City from a fiery fate at the hands of a Norse demon called Surtr. Guest-starring Batman and the evil Firefly, this Prestige one-shot is brought to you by the reunited Batman: Sword of Azrael team of Dennis O'Neil and artist Joe Quesada. Joined by fan-favorite inker and Quesada collaborator Jimmy Palmiotti, this team-up is sure to catch fire!
