Gotham City’s cauldron of crime and corruption is about to boil over. While The Joker remains at large, criminal kingpins and former rivals The Penguin and Two-Face have joined forces – and the mysterious narco-terrorist known as Scarecrow remains unidentified, even as his chemical nightmares plague the city. The schism between Batman and Catwoman grows ever larger as both escalate their separate wars on crime, threatening dire consequences for both. And Harleen Quinzel (aka Harley Quinn) is living for a love that’s slowly killing her, just waiting for inspiration to strike.
