I would recommend this book to girls and boys in middle-school ages and older, and also anyone fascinated by water. I really liked that each chapter is from a different character's point of view. It felt like I was in that world; and the vocabulary was easy to understand. I learned that even people who are different and come from different worlds can get along.
The ending was so suspenseful, I can't wait to read the next book. I can't think of anything I didn't like about it.
I really liked this book; it is the best book I've ever read!
