Summer has ended, but the heat will not let up. Ash has covered everything. Weeds and wheat grow around the cars abandoned in the road. Anna and Astor live in the house behind the fence, surviving in a world stripped of adults. The rooms are piled high with rubbish. Their mother's skeleton lies perfect on the bed. And every few days, Anna must head out beyond the fence for provisions and medicine. Each time she goes, she may never come back.
