"The Tower", begins

Arkham Asylum has fallen, and in its place, Arkham Tower has risen in the heart of the city, a pitch made by the mysterious Dr. Wear. Unlike the Asylum, Dr. Wear promises his methods and drug treatments will heal Gotham’s criminally inclined for good - a claim that skeptics like Deb Donovan and the Bat-Family don’t believe. There’s something wrong with the tower, with Dr. Wear’s methods - and with Batman away from Gotham City, the rest of the Bat-Family is going to find out what...but not before everything explodes.
