So you know Harley Quinn and the Joker right? Well they have a daughter but Joker doesn't know. So Harley gives her daughter to her sister, Veronica. Harley's daughter was named Lucianna Quinzel. She applies for a job at Arkham Asylum at the age of 16, and that's where she met Jerome Lush. Lucianna falls in love with him. Not going to say the rest because I don't wanna spoil! I hope you enjoy Pretty Little Psycho.
