If you're simply looking for history in a kid-friendly format, I could see recommending this book. But as a story, no, I'm sorry, it "missed the boat." With the exception of Magellan himself, the characterizations are pretty flat. The plot doesn't follow a good trajectory, with repeated climaxes after which the story continues to lumber on. The hero, Mateo, does grow throughout the story, but not in any way that shows that the author is on top of her craft. I had to make myself finish this book. It's not horrible, but it's also not worth more than a lukewarm review.
