First: I didn't read the description of Paper Girls before I started reading. As a steady fan of Saga and others like it, I just trusted Brian K. Vaughan and Image Comics to intrigue me.
I don't know what I expected -- a realistic drama about paper delivery girls on some adventure. For some reason, I wasn't expecting science fiction, some creep-tastic moments, violence, and a fight for survival. And while all of those things are kind of minimal, they're handled with a realism and emotional gravity that each situation deserves.
I loved it.
I'll edit this post more later when I have more time, but for now I'll just say: read this! If this is an ongoing series, I look forward to what they do next.
