Penryn, her mother, and her sister are among the few who survived in the new world. Life for Penryn— even before the apocalypse—was hardly easy: her sister Paige is confined to a wheelchair, most likely because of their mother’s schizophrenia, while their father left the family after that, officially “an unfortunate incident.”
Now even more responsibility hangs over Penryn. When the family ran out of food and gangs became even more brazen, they had to leave their shelter. On the street, they ran into an angelic skirmish, where another angel had cut the wings off one of the angels. The girls accidentally drew the attention of flying warriors, and they took Paige with them while their mother, frightened, ran away. The only thread Penryn has to search for her sister is a wingless, half-alive angel.
