Red Rider's Hood — Neal Shusterman

Red rides around his tough urban neighborhood in his blood red Mustang. It satisfies his urge to wander, and it usually keeps him safe from the gangs in town, the Wolves and the Crypts. But when Red's grandmother is mugged by some members of the Wolves, Red can no long sit on the sidelines. He decides to join the Wolves as a pledge so he can learn how to defeat them. Soon he uncovers their terrible secret: they are werewolves with a thirst for human blood. Instead of feeling horrified, Red envies the Wolves' freedom and power. Even as he trains to kill them-- under an unlikely but cunning werewolf hunter--he has come to see them as packmates. Finally he is faced with a choice at the next full moon: take up the Wolves' murderous ways, or take them down.
