I like this book because it shows you that you can believe in what you want. Billy believed the mermaid needed a real home and not just live in a tank. My favorite character is Billy. I like Billy because he is adventurous, even though sometimes he gets scared. My favorite part of the book is when Dr. Deep's assistant sends the mermaid away for money. I liked this part because even though Dr. Deep's assistant was very sneaky, he wanted to use the money for a good cause.
I would recommend this book to all third graders. I know most of you like scary books and mysteries. This book is so scary that it might make you shiver!
