For an American Girl book, this was pretty good. It definitely wasn't the BEST book I've ever read, but it wasn't the worst either. In fact, it was actually a pretty enjoyable read!
Plot: Lea is a tween who loves photography and animals. Her brother, Zac, works in South America rescuing animals from poaching situations. In Books 1 and 2, she visited South America and made a friend there, Camila. In this book, Book 3, she isn't coming to Camila- Camila's coming to her!
Positive content: Good lessons and a great mystery.
Negative content: The only thing that really irritated me about this was that at the end Lea said that her was no job of greater importance than saving animals. Okay. Sure, saving animals is great and all that, but it sure as anything isn't the most important job out there. What about a surgeon, or a fire-fighter, or a policeman? Human lives matter!
Conclusion: A good read.
