After surviving a massive earthquake and completing a desperate race halfway across the continental United States, Captain Mike Andrews and the crew of the newly-rebuilt Self-Contained Exploration Vehicle Four have a new mission: continue the search for life in the Pacific Northwest.
After weeks of searching, they find what they were looking for: the small town of Sherwood, north of the ruins of Bend, Oregon. The tiny community populated by forward thinkers, survivalists, and specialists has managed to not only survive after the Sixty Minute War, but thrive. Andrews, Mulligan, Eklund and the others are amazed at the discovery, and the residents of Sherwood are enthralled to discover there is still a functioning remnant of the United States working to restore our once-great nation.
But following the crew from Harmony Base comes a monolithic threat. A ragged, violent army emerges from the nuclear landscape. Its objective: to conquer Sherwood and take everything they can get. Andrews and his team are the only obstacle in their way.
