Ash. Siblings Josh and Claire were out with a detail of locals trying to replant the Selkirk area following the previous summer's fire when the ash hit. They had seen a lot of ash, but not like this. This was a wall two miles high that swept through and buried everything. Everything. Some said it had to be the result of a volcanic eruption. As far as anyone can tell, the two-score people who have made their way to the valley are the last people left alive in the world. Everyone is trying to survive, but Josh is determined to thrive. With Claire by his side, he begins to rally the people to not just claim a life in the ash, but to build a new community. With death all around them, and continuing to come their way, Josh begins to wonder if he can keep everyone going long enough to build something new. Even if he can keep their hopes up, how long can they push back against the ash? From the ash arises a new town, a new way of life, and hope.
