Rumble by Ellen Hopkins

Rumble is a fast-paced and emotionally gripping story told in verse.  At the center is Matt, a teenager struggling with his anger against all of those in his community--parents, school counselors,  and friends, who failed to help his younger brother, who was mercilessly bullied for being gay and who committed suicide.  The only person who can take him away from his grief is his girlfriend, Hayden, but she is becoming increasingly preoccupied with her church group, a fact which further enrages Matt because he does not believe in any god who would let his brother suffer and die.  Hopkins pulls no punches when talking about the issues Matt faces--parents splitting up, homophobia, teen suicide, gun control, and his own responsibility for Luke's death.  Matt is a character easy to root for and to hate.  This is a great read!
