John Constantine, Hellblazer: Shoot

A single, potent issue from DC, this 2014 one-shot written by Jason Aaron with art by Sean Murphy takes aim at the American culture of gun violence. It follows a traumatized school shooting survivor who, after moving to London, becomes entangled with the cynical magician John Constantine. The story matters as a stark, standalone political statement from two celebrated creators, using the horror genre to confront a real-world nightmare.
