Loved it! It makes me want to be an artist and a fencer and learn languages and go on adventures like Cabrill, Austin, Po, and (especially) Skye.
The characters have their own personal motivations. They drive the plot. They struggle with what other people want them to do and expect them to do, and what they need to do to be true to themselves. Something interesting and significant happens in every scene. The serious parts are balanced by fun and funny parts.
