All American Girl by Meg Cabot

This is the first young adult book by Cabot that I have read. I really enjoyed it. I felt it was funny and a great light read. This girl Sam, who goes to a prep school and doesn't fit in at all - she somehow saves the President of the US. All of a sudden everyone is trying to be her friend and get her attention, including the President's son. What is a girl to do?!
