Harley Quinn Vol. 1: Hot in the City (The New 52) - Amanda Conner, Jimmy Palmiotti
Having slept on it and revisited a couple of issues I'm downgrading my original rating to 2 *.
A fabulous beginning is let down by a flagging sub-plot in the middle. Some wonderful art in the innovative first issue, but average for the remaining ones.
