Gotham City Sirens

When Catwoman suggests that Harley Quinn return to her old life, Harley, now free of her abusive relationship due to Joker' s death six months ago, agrees and begins working on her reformation. But Ivy puts up a fight, believing the decision to be stupid due to Harley's violent nature. Harley decides anyway to become Harleen again, but it doesn't last. Quinzel, now living in Brooklyn with her sister and daughter, hears a rumor going around that the Joker is alive. She knows this to be untrue, she watched him die... But the constant reminder of Joker's death sets her off, and the clown princess of crime is back once again. Ivy and Catwoman use this opportunity to try and get Harley to work with them again, but she declines. But when Catwoman is framed for a series of brutal murders, it's up to her alter ego, Selina Kyle, to look for the real killer. Ivy agrees to help her, and they eventually convince Harley to join them. Together, they search for the true killer, and in doing so, discover a chilling secret beneath the streets of Gotham city.
