Do you think you'll ever go outside of the established raunchiness of your books? I don't mean a murder sex party, but you know, straying a bit into the dark and gritty. It's just my opinion but I feel like you play it a little safe. Not necessarily a bad thing though!
I don't think I've crossed the line where I'm personally comfortable doing, but I think I'm close. Usually, I give a few characters (like Wayne) the ability to go further than others, as an acknowledgement that there are good people out there who don't happen to have my same prudish nature.
I think the thing you'll see that is the closest is when (and if) I write the Threnody novel.
For everything else, you'll have to settle for knowing that one of my quirks as a writer is that I do indeed play it a little safe--and probably will always do so. I'm very aware that my children, nieces, and nephews read my books. Beyond that, I feel that I'm an intentional and specific contrast to other writers in the genre--I consider it my duty to prove that (like many of the classic movies) you can write something that is for adults, and has depth, without delving into grittiness.
This is not a disparagement of people like Joe Abercrombie, who I think is an excellent writer, or others like him--and I'm glad we have them in the field. However, my own path goes a different direction, and I think it's important that I also publish, proving to those who perhaps wish to be more circumspect in these areas that there is a place for them in the genre too.
Does that mean that you recognize that the stories that take place on Threnody, a world of your creation, are stories that you are uncomfortable exploring because they are too harsh or intense? If that's the case I find that absolutely fascinating and very impressive- it's almost as if the Cosmere is a real place with real people and you're just communicating their stories to us. I personally would rather you never told those stories instead of forcing them to be something that is untrue to what you created them to be.
A writer must be willing to do uncomfortable things; I fully believe that. Stories like Snapshot (my most recent novella) have done this before, and if I write the Threnody novel, I intend to do it well. (But also be very clear to audiences that it's darker than other cosmere books.)
It's not about intensity--I feel other books are intense. Or even about violence or darkness. It's about how far the narrative needs to delve into these things, or the relationship of light and hope to the darkness.
Dalinar's backstory in Stormlight is uncomfortably dark, and I won't pull punches from it. But it's balanced by the man he has become. In Threnody, some of the stories don't have that balance.
