This was quite a fun book. It felt a bit short, though, probably because of the target audience and the straightforward plot. I would have liked to learn more about the world and the technology, as well as the history of Rithmatics, how exactly it works, and what's up with the tower in Nebrask. The characters, though they felt simpler than other of Sanderson's work, were still very fun, especially Melody. I look forward to hearing if Sanderson writes any more novels set in this universe.
