Is Mie, from the "Clique" book series, SUPPOSED to be a horrendous, shallow little "b-word"?

Yes, Mie is a little brat. I only read about the first 6 books or so in the series, and have not read the one you are talking about. However, when I was younger and read the books, I honestly found them to be fun. Hey were just mindless entertainment. And, really, nobody in the book even likes Mie. While everybody looks up to her because she is rich and powerful, I do not think her friends even actually like her. I do not think the books are realistic, although I am not rich enough to know, but there is just something fun about them. Mie is mostly just a character who people love to hate.
