Diary of a Witness — Catherine Ryan Hyde

One day, something's going to snap. . . .

Ernie doesn't have a lot of friends at school. Just Will. They have stuff in common -- like fishing. But more important, they have common enemies: the school jocks, who seem to find bullying just another sport.

For the most part, Ernie and Will take life at high school in stride. Until Will has one very bad day. Now nothing is remotely funny. Ernie finds himself a witness -- to loss, to humiliation, and to Will's anger -- an anger that's building each and every moment.

Ernie doesn't want to believe his best friend is changing, but he can't deny the truth. Soon he has a choice: join or die. Or can he find another way?
