Massie Block 

One of the main characters in the popular tween girl books, The Clique Series, by Lisi Harrison. Massie Block is the "alpha", or first-in-command of the girls' clique, The Pretty Committee. She is pretty, with glossy brown hair and amber eyes, but mostly known for her attitude and schemes to get herself (and her clique) more popular. She's rich, like the other members of the Pretty Committee (exluding 2, Claire Lyons and Kristin Gregory), and stylish.
As stated on the back of the first book, Massie knows you'd give anything to be just like her.

Girl: I wish I could be Massie Block!
Girl 2: Me too! She's rich, popular, and pretty!
Both Girls: YIPPEE!

Clinton-Massie 

The school that is full of people that think they are better than anyone else, the teachers and principals aren’t to bad but the students are ridiculous and downgrade others for how they look, talk, and act.
