Danger on Midnight River (Gary Paulsen World of Adventure, 6)

When his camp van crashes into a raging river, Daniel Martin is plunged into a frightening position. Suddenly the campmates who call him "dork breath" and "retard" because he is a slow learner are depending in him for survival. Daniel could save himself. Or risk everything to try to rescue the bullies too. Night is approaching, and desolate mountains surround them. Even if the boys do make it to shore, their dangerous ordeal is just beginning.
