The Future Second by Second - The Shelter Trilogy

In a new America where civilization as we know it has ended, every hour counts. Everything is ticking along perfectly in the sanctuary community of Osto until a band of raiders arrives intent on violence. Vasha has led her people through the worst the world has to offer for years, but this new threat could destroy her hope for the future. She's forced to strike a bargain with the leader of the raiders as tensions rise among the survivors and refugees who call Osto home.
Old rivalries and prejudices put everything they've worked for at risk. But if Vasha plays this right, she just might forge a new future for Osto.
