I love the concept of this book. The idea of people grouping together to survive has always held my interest. However, there were a few places that need to be fixed. I was a little turned of by the fact the teens and adults seemed to pair up, exclusively. Every adult was paired with a teen, and I can't remember any paired with other adults. Why didn't the handyman and the farm lady get together? Nope, both got with teens. Another thing is the fact that all the things and people they needed seemed to crop up just when they needed it. They needed to build, oh, look, a handyman. Someone is hurt, here's the doctor. Everything is in order, we should build a democracy, oh, and here's the army to help. This book is what I would class as fantasy survival, because they don't really have to survive much. They seem to have everything they need, even solar panels and seeds to grow food. I did like the ending, but I hated the fact that Mike let his leadership go after he made all the decisions that kept everyone from killing each other.
