Big news today: White Sand, an unpublished cosmere novel, is going to become a three part graphic novel series, the first coming out next year.
White Sand was the first novel Brandon ever wrote, and he eventually did a complete rewrite of it around the time of Elantris. That version of White Sand was good enough for Brandon to get his agent, though they decided to submit other works instead. White Sand was to be the first in a planned trilogy, but Brandon was never satisfied with how the plot turned out originally, but we now we'll finally get to see it and its world.
