It's been months since Dr. Harleen Quinzel began interviewing criminals at Arkham Asylum, and she's having strange dreams about one of them in particular: The Joker. What starts off as nightmares will soon evolve into fantasies. Despite warnings from the Dark Knight himself, she's utterly fascinated by this man who seems the perfect expression of her theory; who says all the things she needs to hear; who seems to know her better than she knows herself. Harleen is a bold new reimagining of the origin of one of DC's most beloved characters, as envisioned by writer/artist Stjepan Sejic. Collects Harleen #1-3.
