Another fun, light read from Sanderson. His approach to "magic" is even more machinistic that in the Mistborn books, and the steampunk aspect is a bit facile. This is a YA book with a preposterous premise, but I can forgive it because the plot and mystery carried me along.

I'd happily give this book to a young reader as a morality tale. There's a charming friendship between a boy and a girl, dealing with class differences, examples of mentorship from adults, and the novel idea that you can do a lot of good with hard work without being the chosen one.
