This book is geared toward a teenage audience, but as an adult, I really enjoyed it. The story takes you through the journey of a group of kids at a camp in the mountains who are cut off from the rest of the world by a deadly fog. They create their own society with their own leadership and laws. They have to deal with weather, providing food, fighting off boredom, protecting themselves from dangerous people in the area and many other challenges. It is about team work, making difficult choices and focusing on the future.
