A tale of life and death in Gotham City. After years of vigilante crime fighting, Batman prepares to become an official Gotham member of the Gotham City Police Department, deepening the rift between himself and Catwoman, who's been using Gotham criminals as her personal ATM. Meanwhile, Two-Face is deteriorating, his two halves at war and his obsession with duality out of control -- which his rival the Penguin is more than happy to take advantage of. The Riddler, after years in the shadow of Batman's A-list foes, is desperate to have his work taken seriously. And the Joker has big, big plans for Valentine's day...

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.
