After months of anticipation and fear, the war with Gryphos has finally reached Ponyville, shattering the fragile peace. Scootaloo and the other Crusaders, now separated from their families in the chaos, have holed up in the Golden Oak Library, hoping to ride out the war until it passes.
But they aren't soldiers; they're just kids who have few survival skills to speak of and barely know how to defend themselves. With bandits and looters roaming the streets and no end to the fighting in sight, the constant struggle to survive becomes desperate as each day demands ever more from the inexperienced fillies and their dwindling supplies.
What will they do when their food runs out? Will the shells ever stop falling? And what deeds will they be forced to commit if it means they can survive just one more day?
