Over the course of her illustrious and very high-class career, Harley's met pretty much every super-villain who ever worked in Gotham City. Some hate her. Some love her. But none of that's gonna matter once they see how many zeroes there are on the bounty The Joker's offering for her head! Sorry, Harley-it's just business. Your next of kin will understand, right? Meanwhile, Cassandra Cain finds herself in the unenviable position of being Harley Quinn's bodyguard...but this could be her opportunity to learn a little about, y'know, loosening up? If she's currently wound too tight, then just sit next to Auntie Harley...she's got more than her share of loose screws!
