Promethea, by Alan Moore. "You can’t really “get” comics until you’ve read something by Alan Moore. He’s not always the most feminist-friendly writer in the world, but his work does amazing things with the medium. Promethea gets overly preachy (and if you ask me, kinda boring) in its later books, but its beginning is a great depiction of a strong female character and a unique representation of shared female power. Also, it’s worth reading just for JH Williams’ amazing art."
