Titan Arum you said --
I would recommend Elantris then Warbreaker. Because Warbreaker is great to read right before Way of Kings and Words of Radiance, for reasons that I would hope are obvious to many.
Uh oh -- It's not obvious to me and I've read Elantris, Warbreaker and the two Stormlight books!
So far, I haven't been very good at putting all these worlds together. What connection did I miss between Warbreaker and WoK/WoR?
