Meg Michaelson and Vaughn Williams find themselves in a post-apocalyptic future where an electromagnetic pulse has rendered modern devices useless and most people dead. They travel south to avoid the winter cold and find a group of survivors at a Texas ranch they call New Eden. Food, fuel, and supplies are scarce. Worse, outside forces threaten the community. That's not the only worry. Meb and Vaughn have secrets they fear will be exposed.
