Parents need to know that this is a modern, graphic novel take on the Nancy Drew stories with few words of substance but great illustrations. Nancy and her friends encounter some scary-for-a-second situations (getting chased by a large lizard, for example), but the drawings never show blood or anything very frightening.
Positive messages:Nancy uses logic to solve this mystery. As the title infers, this graphic novel slips in educational snippets about the environment and its inhabitants such as "Did he have hollow hair like a polar bear," "I was impressed to see that despite all of her money, she drove a little hybrid, almost like mine," and "He cared nothing for the rivers and skies he destroyed for the coming generation."
Violence:Nancy and pals fight mythical creatures, but the cartoons don't show blood or anything scary. The scariest thing is the creatures' big teeth.
Language:There's only one line that may offend: "Some thanks for saving your mangy butt."
Consumerism:The novel has some ads for the other graphic novels in the series -- and even a few pages of the next novel to get you hooked. There are also promos for a Nancy Drew video game, the Hardy Boys series.
