re: Need new author/series suggestion in Fantasy.

If you want to try out Brandon Sanderson, just try the original Mistborn trilogy, then figure out if you want to get deeper. These were his real breakthrough, I wouldn't start with Elantris which was fine but is a lesser book and completely unnecessary. The relationships between all his books only became an issue much later in his bibliography (which I think was a huge mistake but that's another conversation).

The Final Empire
The Well of Ascension
Hero of Ages
