I wrote and drew my own books on notebook paper, and I'd staple 'em together. I had my own fictional company, and we had our own thinly veiled offshoots of whatever was popular at Marvel and DC at the time.

I like to think I grow as a writer from every new experience.

'Ghost Rider' definitely has an appeal that's far beyond comics.

I love characters who are kind of haunted by their pasts, who struggle on despite their flaws, knowing that, at the end of the day, they're not going to shuffle off to those pearly gates.

If you liked my 'Ghost Rider' run, you're going to love what they're doing in 'Punisher.'

I think it's our job as writers for Marvel Comics to continue to create those type of stories that can be mined instead of just trying to give readers exactly what they see on film.

'Original Sin' is one of those ideas that has been circulating for several years at the Marvel retreats we have a couple times a year. We have all these ideas floating around for a bit before we figure out how to align them.

We had that first Marvel NOW! retreat where everybody came in and pitched their new books, which was probably the most exciting retreat I've ever been to because it was all brand new.

An important part of any good mystery story like 'Original Sin' is that it's not just a game of 'Clue' with surprise after surprise after surprise, but the goal is to tell a story in the midst of that. Even once you know the solution to the mysteries, it's far from the whole story.

'Original Sin' is, for me, a murder mystery with a huge cast that plays out on a grand stage.
