A young psychiatrist with a possible cure for the madness haunting Gotham City, Dr. Harleen Quinzel must prove her revolutionary theory in a skeptical institution by delving into the disturbed minds of the most dangerous inmates of Arkham Asylum. But the more time she spends with her criminally insane patients, the more she is drawn to a specific patient - and drifts further away from reality.
The birth of the legendary anti-heroine Harley Quinn and the shocking beginning of her twisted love affair with the Joker are revealed in Harleen, a stunning new story of love and obsession written and illustrated by renowned comic storyteller Stjepan Sejic.
