Hidden - Megg Jensen
This book is really good. An isolated community trying to reconnect with the outside world. A life threatening fog that kills off the three people who are sent each year to attempt the connection. Strange practices and traditions that have evolved in the isolation of 80 years, an entire generation. And too much missing information.

But once they reconnect, they have dragons and all sorts of things being reintroduced to their surviving society. But who caused it and who's in charge now? We're they better off back behind the fog?
