I have not long ago finished Books 2 and 3 of this series. A word of warning: you cannot read these books in the bath unless a) you have bigger biceps than I do or b) you don't mind drowning or c) the books aren't yours and getting them wet isn't a problem.
   They are BIG.
   And therein lies my only complaint. You can have too much of a good thing.
   Sanderson did a good job of finishing off the Wheel of Time series; he managed to tie up loose ends and rein in all the petty details that Jordan had got too fond of. And here, in the Stormlight series, I fear Sanderson himself is becoming a bit self-indulgent. You can also tell, occasionally, where he or a reader has spotted a slight inconsistency, and he has papered over the crack. I like the characters; I like the concepts; I like the action. But it's beginning to go on a bit. You can't describe everything about a world, or even everything that happens to a cast of characters. You have to make your choices, as they say in the scriptwriting business. And I feel Sanderson hasn't made enough of them. Choices.
   That said, they're a good read and I admit I want to know what is going to happen in the next - wait for it - seven volumes. If I can stay interested for that long.
