Arkham Asylum is home to many of the Batman’s worst enemies— including the most dangerous one of all: The Joker. No one has ever been able to break through the insanity of the Joker’s mind. Many have been broken themselves in the attempt. But Dr. Ben Arnell is sure that he will be the one to finally cure him. From the creative team of Jeff Lemire and Andrea Sorrentino comes Joker: Killer Smile, a terrifying tale of psychological horror that explores the madness within The Joker— and the family man who will risk it all to gaze into the abyss. But comics and graphic novels have come a long way since the 1930s. A substantial shift at the end of the 20th century towards darker, more adult-oriented fare proved that “funnybooks” didn’t have to be funny to be good. Now, plenty of comics are written specifically for adults as they explore complex themes of sex, violence, and morality. Gone are the days of only bright panels and benign stories. If you’re someone who likes your comics dark, try out these titles that are decidedly not for children!
