I'm not Bob, but I'll have a goelbowlick said:Well, if there was ever an opportunity to ask a question this is it. Hey Bob, can you recommend a non-superhero based comic (that isn't walking dead)?
Transmetropolitan - about a futuristic journo exposing corruption and far more fun than it sounds.
Y The Last Man - a guy and his monkey left the last males on earth after a 'disaster'
Preacher - Just the greatest comic book tale ever told.
Just because I like bending the rules:
The Boys - not superheroes, but they police the superheroes, and keep em in line, and by Garth Ennis, creator of Preacher among others
I also second Bob's recommendation of get thee to a library. (quickly, in the UK, before our government sells them all off, and turns the books into kindling, they've started on the libraries, and they'll see a profit in books as firewood once they've sold all our forests.)
Politics aside, your local library is a great place to get introduced to graphic novels, and even if your local library doesn't do em, you can order them into your local for £1 for a 3 week loan, far cheaper than buying em.
