Stjepan Sejic born November 27, 1981 is a Croatian comic book writer and artist, best known for his work on the Witchblade, The Darkness, and Aquaman among others.

Stjepan's art is very unique in its own way as it is characterized by painting-like graphics which are usually digitally altered with Photoshop and other visual softwares.

Dr. Harleen Quinzel has a theory: mental illness is a survival mechanism. As she seeks to help the broken souls of Gotham City piece together their sanity she will become the one thing she fears the most: one of them. A bold new retelling of the tragic origin of Harley Quinn told through the eyes of the only person who knows her better than anyone: Harleen.

It's been months since Harleen began interviewing criminals at Arkham Asylum, and she's having strange dreams about one of them in particular: The Joker. What start 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 theory; who says all the things she needs to hear; who seems to know her better than she knows herself.

Written and drawn by superstar artist Stjepan Sejic best known for his work on Aquaman and Justice League: Odyssey. Harleen is a bold new reimagining of the origin of one of Batman's greatest foes as she takes her ultimate fall from grace. Think you know Harley? Think again.
