"It's a parallel-universe, Prohibition-era world of mooks and shamuses that is the twisted magic mirror to our bustling Big Apple. It's a city where sinister characters lurk around every corner while the great superheroes who once kept the streets safe have fallen into deadly rivalries and feuds. Not that its colourful residents know anything about the real New York ... until detective Rad Bradley makes a discovery that will change the lives of all its inhabitants."--Page 4 of cover.
