I would say that I personally can’t stand politics in the real world or in stories so I am with you on that and I don’t believe any of the cosmere stuff focuses on politics at all. Dune is something politic heavy and whilst I made it through it eventually it took me four or five tries and I probably wouldn’t return.
I highly recommend trying out at least the first mistborn book to see if you like it if you get to a point where you are in need of something else to read after you’ve worked your way through some other suggestions.
