Harley Quinn, Vol. 3 #42B
Old Lady Harley"! In this far-flung future tale, Harley returns home thirty years after leaving Coney Island -- or, more accurately, she's DRAGGED home -- to deal with the mess that the Gangs of Harley have made in her absence! Her disciples have all splintered into warring tribes, and they've torn down what's left of ravaged, mutated New York City in the process!
