I have read a few of Sanderson's books, Mistborn, Elantris, WoK, Rithmatist, Legion, Warbreaker, and I am reading WoR. I was thinking about rereading some of them. I heard about this cosmere thing, what is it and please point me to where I can learn more. In what order should I read the books? Please include anything else you might think may be helpful to me. Thank you
