I've just finished reading Words of Radiance and plan to read Oathbringer when it comes out. A friend recommended Stormlight only, and now that I have I feel like I've ruined the order in which to read all of Sanderson's other work for the cosmere - all the reading orders have books before and in-between TWOK and WOR.
So, can anyone help me out in determining what books to read next, in order to gain a greater understanding of the cosmere and so I don't miss out on re-occurring characters?
