Good and evil are so close as to be chained together in the soul.´ - The Strange Case of Dr. Jekyll and Mr. Hyde by Robert Louis Stevenson. Harleen Quinzel is many things, a gymnast, anxious, broke...but the last thing anyone would call her is evil. Harley Quinn on the other hand... When Harleen signs up to participate in a clinical research trial with her girlfriend, Pamela, the most she can hope for is extra cash in her wallet and a chance to get her anxiety under control. But what she gets instead are increasingly larger gaps in her memory and stolen mementos from some guy named Jack she´s never met. Soon, Harleen discovers she´s sharing her life with Harley-a take-no-prisoners, who-cares-about attendance, maybe-we-oughtta-save-the-bunnies kind of girl. She is the opposite of Harleen in many ways. She is anarchy in a cute dress. And although she´s throwing Harleen´s life completely off track, maybe she ain´t so bad either... New York Times bestselling author of Wicked Lovely, Melissa Marr, teams up with celebrated artist Jenn St-Onge to tell the story of a girl who will learn good and evil are not black and white (and red)...as long as she doesn´t get caught.
