Sanderson is definitely my favorite Author. I've read most of his stuff (Minus the Alcatraz series).
If you guys haven't picked up the new "Arcanum Unbounded" it's great. I had many of the included stories already, (Emperor's Soul, Shadows of Silence, Secret History) but there are new stories. There is also a foreword and afterword about each, where Brandon discusses how the story fits into the cosmere a bit.
The Lift Novella is soooo good. I love her. Also, reading White Sand as a novella after reading the graphic novel was cool. There is also a short story about what's going on in within the city of Elantris (The Hope of Elantris, iirc) while the novel is following along outside of the walls.
The dude is a writing Machine. I can't believe how many quality words he publishes in such a short time.
Also, I'm super excited that DMG Entertainment has signed a licensing deal to make the Cosmere into a film & TV universe!
