Shattering Glass by Gail Giles
Simon Glass is a nerd. Clumsy and awkward, he's a loser who occupies the lowest rung of the high school social ladder. Everybody picks on him, making jokes at his expense - until Rob Haynes shows up. Rob, a transfer student with charisma to spare, immediately becomes the undisputed leader of the senior class. And he has plans for Simon. Rob's mission: To turn the snivelling Simon Glass from total freak to would-be prom king. But as Simon rises to the top of the social ranks, he shows a new confidence and a devious side that the power-hungry Rob did not anticipate. And when Simon Glass uncovers a dangerous secret, events suddenly darken. The end result being disquieting, chilling ... and brutal.
