Mermaid Marina by Lesley Rees, is an attractive board book, filled with whimsical sparkly illustrations. It's intended for children aged three to six. It's one in a series of four books.
While the pictures are attractive, the story is terrible. Marina is a mermaid, who gets ready for a party where everyone is amazed at how pretty she looks. The story itself is poorly written. The values expressed - basically, that your worth comes from how pretty you look and others will like you because you're pretty - are ones that I don't want my daughter to hold. This book encourages judging others and yourself based only on appearance.
While the illustrations are pretty, if you get this book or receive it on accident, just don't read it. Make up your own words. I'm glad I got it at a garage sale; I don't feel too badly about throwing it into the garbage, where tripe like this belongs.
