The literary quality is not stellar, but it's a compentently told story, and in this case, it's not the story that matters. Children will learn facts about the ocean and the life cycle of an octopus, and they will care about what they learn.
Dee Scarr is an experienced diver and naturalist who has put together programs to teach kids and divers about the ocean and its life. This book is a natural extension of those efforts.
Upbeat, cheerful, and informative in an engaging fashion, kids about 10 and under will learn a lot, and enjoy learning it, from this book.

Excellent choice for homeschoolers wanting to include a little marine biology in their nature study.
