The art is fantastic. DC, get Meghan Hetrick on a monthly, stat!
I think this is some sort of transition piece for the character between Catwoman and Batman Eternal. She seems more personally obsessed with the Joker here, where as in Catwoman she was just happy to appropriate the fear he inspired. Also there is nothing about her tribe, the Nethers, in the preview. Don't know if they will show up again.
