I'd have to say the concept of how things are done in this book, are interesting. Using "breaths" for power or senses. And how things are done with the characters, is just awesome. One of the best books I've ever read in my life, so far, Warbreaker brings about a new way of looking at things and a new way of life altogether.

I don't want to say too much on the storyline cause I might ruin it, but still have a look if you will. It's well worth the read.
