OK, I’ve never read Brandon Sanderson, where should I start?

I’ve never read legion but have read the Mistborn series and the Stormlifght Archives and really enjoyed them.

Mistborn The Final Empire is where I started ? it’s the first of a trilogy. You could also start with one of his standalones – Warbreaker or Elantris. The Stormlight Archive series is my personal favorite. It’s his epic fantasy series set to be 10 books. The first 3 are out right now – starts with The Way of Kings.
