Harley Quinn has been transformed, and she wants the world to know! She's ready to shake things up once more - and this time, the gloves are off! Harley Quinn has avoided Gotham City ever since she broke up with The Joker - she found a home, and a kind of family, in Coney Island. But when she gets an offer she can't refuse, she has no choice but to slip back into the city as quietly and quickly as she can, before anyone - especially her ex - learns she's been there. But for Harley, 'as quietly as she can' is plenty loud... and before she can say 'Holee bounty hunters, Batman,' The Joker's sicced every super-villain in the city on her pretty ombrÔe head! And she only has one hope - it's the only team tough enough (or crazy enough) to come to her defense - The Birds of Prey.
