A comic book industry event: a new original ongoing superhero series from Mark Waid! IRREDEEMABLE dares to ask the question: what if the world's greatest hero decided to become the world's greatest villain? Heroes are being picked off one-by-one in a brutal and viscous assault. They never stood a chance - never saw it coming. A small cadre of heroes race against time and space to stay alive and turn the tables. A "twilight of the superheroes"-style story that examines super-villains from the writer of KINGDOM COME and EMPIRE!
