Kate is a senior at Millbank High School, and not happy with her life, but content. Then she finds out that every senior girl is ranked online through a system called the Millbank Social Stock Market, and becomes obsessed. She's number 71 of 140 girls.
So Kate and her friends Dev and Cal get together to change her stock. They change her image and she changes her attitude in the last few weeks of high school to see what they can do to change her stock. They also join the stock market--at $500 a pop--to invest in her. The winner gets $25,000, and they're hoping they can accomplish that.
This is not your typical chick lit book, however. There is a sort of happy ending, but not the typical-girl-wins-guy-and-everyone-is-happy ending. However, this is a very interesting story and ending.
