I liked this book because it was adventurous and there were lots of mysteries. You never knew what was going to happen - whether it would be good or bad. I liked all the characters especially the sea creatures because they sounded cute. I think it would have been fun to have had them as friends to play with. I loved the conclusion because I did not know what was going to happen. I think that seven and eight year olds could read this book to themselves but under this age that parents could read to them.
