Isabel has always felt different, like she will one day do something important. But the thing is, she doesn't know what important thing she is going to do. That all ends when Isabel goes on a whale watching trip with her 5th grade class and falls overboard. The whales start tp circle around her and to Isabel's amazement, she can understand them! After learning that she is a Chosen One, a mermaid that is in the form of a whale that is to teach the whales, Isabel is taught many new things, while becoming more and more aware about the dangers, and has many exciting adventures. But when her tail gets infected, Isabel must make a choice that will rip apart she and the whales. Lightly sprinkled withh romance, this book was so enjoyable! But I wish that the author could write a sequel because the ending isn't complete. This book should have won awards but it hasn't which is suprising. I hope you read this because this is a must read.
