Aquamarine is a really high interest read for girls in 6-12th grade. Most of my students liked the movie better than the book, so it is interesting to note the differences between the two because there are a lot! This book is about 2 best friends that are going to be separated after the summer. They end up meeting a mermaid that changes everything for them! If you like summertime, the beach, and boys, then you will love this book!
