Frankie Stein is not a average teenager. Aside from the fact that she’s only 15 days old and that she has bolts in her neck and a green tinge to her skin. Life does not seem hard for her,does it?Lisi Harrison’s book series is definitely aimed at the younger end of the teen market. `Monster High’ is a bit of unabashed pop-culture fun for tweens.
The monster kids rock out to Lady Gaga and the Black Eyed Peas. They have freaky fabulous wardrobes and say things like `that’s VOLTAGE!’ But if you read beyond the cool, unique stuff that they have, they have to face the fear of there group getting shown.
I really liked the character of Frankie Stein. She looks different, she loves to be her self and wants to show her greenness and she desperately wants to fit in. But she never sacrifices who she is for how other’s will see her. It’s a hard lesson she has to learn, but Frankie has a great sense of self, bolts, green skin and all! I recommend this book to about twelve and up because it is a little bit on the mature side but it is a fun book to read!

I loved this series in middle school. I feel like the picture books, tv show, and dolls made the books seem childish, which is why many people didn’t read them, but the book series was a totally separate young adult entity.
