Literature Analysis - Something

It's funny how the current book I am reading can relate to everyone, mostly in high school. In this book it starts off with two friends. They were the best of friends in middle school, until high school hit. Darcy began hanging out with a group of students that Brisana despises. Darcy's actions lead to them being the worst of rivals. Brisana constantly making bad remark about Darcy. Darcy always remains the bigger person and ignoring her, but all of that changes once she finds out that her friend is going after her boyfriend.
