"Some mysteries just don't want to be solved! As Harley digs deeper into the death of her friend, it becomes clear that there are forces in Los Angeles that don't want her this close to the truth. Will Harley be broken by the City of Angels, or will she be able to avenge her friend's death? And will she be able to convince Booster Gold that he is not her crime-fighting partner and never will be?"
