The story of young female warrior who must start a revolution if she and those she loves are to survive. Orpen has always been an outlier in Phoenix City - the only outsider ever admitted to the ranks of the banshees, the female warriors who enforce order, and protect it from the skrake - the ravening creatures that have laid waste to the rest of the country, and gather at the city walls. Unrest is building in the city - a deadly sickness is spreading through the workers, while an unspoken disillusionment is creeping amongst the fighting women, weary of enforcing the all-male management's patriarchal rule, and of the cost, to their sisters, and to young new recruits, of upholding this order. Rumour has it that banshees have been taking matters into their own hands, and taking swift and violent revenge. When Orpen's troop leader falls under suspicion it becomes clear that Orpen will need to muster all her courage and prowess if she and her fellow banshees are going to be able to find a way to escape, and rebuild a society worth fighting for.
