Hannah is a typical high school senior. She is popular, valedictorian of the senior class, captain of the volleyball and cheerleading squad, and has everything going for her. Her class is considered the life of the party, and the ones to call to liven up any event--that is, until they weren't. Tragedy strikes this close-knit group as the second semester of their senior year begins. What lessons will they learn? Will their friendships last the year? How will their choices affect the lives of others?
