Now, in the ruins of post-apocalyptic Paris, this fallen angel is struggling to keep Bastille afloat amidst a never-ending series of disasters. His only hope in stopping the relentless cycle of destruction rests in Kara, a woman he'd betrayed years before and leader of a mysterious band of scavengers who have somehow escaped the curse's influence. Ash needs to learn her secret if he has any chance of success, but is Kara their salvation or his downfall?
