So, Zack Wilson thought, almost laughing at himself. I've been at Camp Wolf Trail, what? Ten minutes? And already I'm having an adventure. At last! Being at Camp Wolf Trail is a dream come true for city boy Zack. Finally, he'll have the summer full of wilderness backpacking, rock climbing, canoeing, whitewater rafting, challenge, friendship, and fun of which he's always dreamed. But nature has surprises in store for Zack: animals, weather, and even the earth itself don't behave he way he expects them to, and especially not the way his favorite book, The Outdoor Adventure Guide, has described them. After Zack makes a mistake that nearly costs him the friendship and trust of his cabinmates, he loses confidence in his book--and in himself too. When a scary catastrophe happens, and Zack is faced with life-threatening danger, will he have the courage and problem-solving smarts to lead his friends to safety?
