A nice asshole.
There are a few Wax and Wayne books that follow in the same world as Mistborn, just a couple hundred years later. I think that one is also a trilogy. I’d probably read those as you’re familiar with the world and magic.
Edit: Oops, I forgot about The Well of Ascension, which follows after the Mistborn series but is before the Wax and Wayne books. So I’d read that one next and then move on to Wax and Wayne, trilogy which starts with Mistborn: Alloy of Law.
The Stormlight Archive series only has three books and won’t be complete anytime soon, but they’re very good reads. The third one got mixed reviews but I enjoyed it. That one starts with The Way of Kings. Different planet, same universe/cosmere as the mistborn stuff (not sure if you’re familiar with cosmere).
I just read The well of Ascension as part of the Mistborn Trilogy. Wax and Wayne books look interesting. Is there a chronological order?
