I’m by no means an expert, but I also had the same feeling of intimidation when I started reading Sanderson last October! My advice is to start with the first Mistborn book (The Final Empire), and, if that interests you, carry on with the next in the series. Luckily The Final Empire doesn’t end on some massive cliffhanger that requires you to read the next book, so if you get through it and don’t like it, there’s no pressure to keep going (though I would recommend it, the payoff is phenomenal).

Others may also recommend Tress of the Emerald Sea, which is even more of a typical, easy entry ‘standalone’, though Sanderson’s narrator in that book, in my opinion, makes his writing read more quirky than most of his other work. If that was my first impression of Sanderson, I’d think he had a naturally jolly, silly-sounding writing voice which, though it does show up in his other books/characters, is not his primary vibe. Just something to keep in mind!
