The books feature a lot of steampunk technology in them, how much of that is based on existing technology, and how much of it is your own creation?
I’d say it’s about 50/50. I like to sneak in crazy Victorian gadgets that actually existed whenever I can, or modify them to suit my needs. Some of the technologies in my books are built out of flawed Victorian scientific theory that I made real. Some are more modern. There’s a cable transport in Blameless based off experimental US military research from the Korean War. But the rest of the time I just make things up, or go running to some of my techy or RPG friends with a plot problem that needs a steampunk solution.
