I love Sanderson's writing, and he's really got a younger voice distilled to a superb art now. David's tone, language, and puns are right on target, even when they're so totally bonkers. There was a point where I wondered just how credible his sense of weaknesses really was, but that was utterly swept away in the thrill of the plot and the action. I think this is probably Sanderson's best young adult work yet, and that's really saying something because his others have all been wonderful, too. I suppose there's no other word for this book, though. It's ... Epic.
