I really, really liked Elantris.....keeping in mind it was BS's first published novel and a single book (which does limit an author's ability to have grand scope). I actually read Mistborn prior to Elantris and it was very interesting to see "where" Vin et al came/grew from.

Yes, the twists and unexpected events are very well done. And let's all be honest, unexpected events that make sense are extremely difficult to pull-off. BS staked the entire Mistborn trilogy on a surprise (or at least unexpected) ending and it worked wonderfully. He is a very talented author.

FYI - reading Warbreaker right now.....will post a review in a week or two.
